7ZPRR0001 2 - Preface - This instruction manual describes installation method of the NTG-420 Transmitter-Receiver. This manual describes radar system configuration with X-band Radar Antenna and NCD-2247-1B PC type radar monitor display as an example. 1. Selecting the installation position 1) Physical selection criteria • Install the antenna at the center of the mast on the keel line. • If the antenna cannot be installed at the above position for some reason, the amount of deviation must be minimized. And, reinforce the mount base and the platform and take precautions to protect the antenna from vibration and impact at the installation position. • To avoid the radiating section coming in contact with other installed objects while it is rotating, ensure that there is at least 200 millimeters from the swing circle (turning radius) to other installed objects (Fig.1-1). The swing circle of the X-band Radar Antenna is as shown in Table 1-1. Fig.1-1 Installation of antenna Table 1-1 Swing circle Antenna Swing circle X-band Radar Antenna 2825mm min-height 必要最小高さ min-offset オフセット最小 Over 200mm 200mm以上 reinforcing member 補強材
7ZPRR0001 3 • Avoid having a rope or signal flag from winding around the radiating section thereby preventing it from rotating. • Avoid the effects of dust and heat caused by smoke from a chimney. • When determining the appropriate antenna height and installation location, take into consideration the reduction of vibration, the strength of the hull and the antenna mount base, and maintenance properties. • Provide for maintenance space: platform, safety link, hand rail, steps, etc. The lower edge of a radar antenna should be a minimum of 500 mm above any safety rail. • When installing the antenna, select a location where there are the fewest structural objects in the surrounding area so that the capability to drive the motor will not be depressed by the non-equability wind which is likely to rotate the antenna. 2) Electrical selection criteria • The installation height of the antenna relates to the maximum detection distance. The higher is the better. (However, if it is too high, radio wave energy greatly attenuates above the antenna's vertical beam width (the point -3dB from the peak of the main lobe). As a result, it is difficult to detect a close-in target. Sea clutter also increases. Determine the installation height by taking into consideration the weight, maximum length of the cable, and maintenance after installation. • If the installation height of the antenna is low, it is difficult to detect a long distance target. The ship's mast, derrick, and construction objects interfere with radiating beam causing the range that cannot be viewed on the radar display to increase. Generally, the lowest antenna installation position is supposed to be on the A-B line shown in Fig.1-2. In the case of the radar antenna, 2θ equals 20°. Specifically, the antenna position is normally elevated so that the building etc do not interfere with radiating beam. The inside of A point might be blind area due to antenna beam does not propagation. So, if near distance should be covered, antenna installation position must be considered carefully. θ = 10° LABθSea surface Blind are aBuilding etc. Fig.1-2 Antenna installation height vs Vertical beam width
7ZPRR0001 4 • If it is considered that sufficient installation height cannot be provided when the antenna is installed directly on the roof of the building, use a mounting rack or radar mast (Fig.1-3). Normally, when the antenna installation height is less than 2 meters from the roof of the building, provide a mounting rack assembled at an angle frame to install the antenna. When the antenna installation height is 2 meters or higher from the roof of the building, provide a cylindrical radar mast to install the antenna. Consider the convenience of the service staff who take care of installation, maintenance, adjustment, and repair of the antenna by providing adequate footholds to the mounting rack and the radar mast. Fig.1-3 Mounting rack and mast for the antenna • When installing the antenna, select a location where there are the fewest structural objects in the surrounding area so that false images which interfere with target detection will not be generated by signal reflection from other antennas, equipments, and cargos. Only as a guide, note that structural objects should not exist within the range of the vertical beam width (Fig.1-4). Vertical beam width of X-band Radar Antenna: Approx. 20° (±10.0° when the height of the radiating section is 0°). Fig.1-4 Antenna and the surrounding structural objects ビーム幅 Beam width Installation Installation
7ZPRR0001 5 • When installing two or more antennas, antennas in close proximity should have a minimum vertical elevation separation angle of 20 and a minimum vertical separation of 1m where possible, so that those antennas do not enter each other's vertical beam width range. 1m (min)20°(min) Fig.1-5 Installing two or more antennas • To avoid interference with other equipment and to prevent radio noise from generating, do not place the VHF antenna, AIS/GPS antenna, and VSAT/INMARSAT's dome within the range of the vertical beam width. * If there is a concern that structural objects existing within the vertical beam width may generate false images, equip the structural objects with a radio wave absorber. (There are two types of absorbers: broadband type having no specific resonant frequency and narrowband type which can absorb a band with a specific frequency. Use those where applicable.) Furthermore, it is effective to install a metal reflector, which reflects radio waves upwardly, between the antenna and a structural object so that the radar's radio wave will not directly come in contact with the structural object. When the structural objects exist in the surrounding area of Antenna unit, the false echo may appear. The sector blank function is effective to reduce the signal reflection from the structural objects. Because of it can stop transmission. Therefore, it may reduce the false echo appearance. Note: Because most radio wave absorbers have poor durability, some must be replaced every year. When installing a reflector, the area to the rear of the reflector becomes a blind sector. Therefore, minimize the size of the reflector. When the sector blank function set to on, ensure a sufficient view field in the surveillance area. * The above procedures for selecting an antenna installation position are described based on the radar's antenna. Comprehensively select the antenna position by considering other antennas' installation procedure manual, building tower mast structure, strength of the selected position, and vibration. 3) Confirmation during test run
7ZPRR0001 6 If the antenna vibrates a lot during test run, try to reduce or prevent vibration by reinforcing the antenna mount base or using wire stays attached to the radar mast. 4) Others • The design of the mounting platform for the antenna should take into account the vibration requirements defined by IEC 60945. Vibration Frequency 2 to 13.2Hz 13.2 to 100Hz Amplitude +/-1mm +/-10% Acceleration 7m/s2 constant • All installations should facilitate protection of equipment, including cabling, from damage. The cables should be kept as short as possible to minimize attenuation of the signal. • Crossing of cables should be done at right angles(90°) to minimize magnetic field coupling. • Eliminating the interference on frequencies used for marine communications due to operation of the radar. All cables of the radar are to be run away from the cables of radio equipment. (ex. Radiotelephone. Communications receiver and direction finder, etc.) Especially inter-wiring cables between antenna unit and display unit of the radar should not be run parallel with the cables of radio equipment. • Cable should not be exposed sharp bends. • The grounding of equipment units should be carried out according to this manual. 5) After installation After you have completed the installation work, check and test the installation work with customer(s) and confirm with each other.
7ZPRR0001 7 2. Installation procedure 1) Precautions for transporting and storing the antenna • An antenna is a heavy load. Be very careful about handling it. • Do not allow the antenna fall on its side while it is stored or being installed. • Do not apply rope to the antenna in the way that squeezes or deforms the radiating section. • When hoisting the antenna by a crane, do not hoist it by attaching a belt or a rope only to the antenna's radiating section as shown in Fig.2-1. • When lifting the antenna（Fig.2-2）: Wrap a cloth around the antenna's support section located at the bottom of the radiator, and then attach a belt to it to lift the antenna. Fig.2-1 Improper way to hoist Fig.2-2 Lifting the Antenna 2) Installation procedures a) Maintain a flat level surface on which to install the antenna. • Use sufficiently thick steel material and reinforcement material for the antenna's installation surface (mount base) to reduce vibration and impact. Keep the mount base flat and smooth. • If there is a partial gap between the mount base and the antenna chassis's legs, work on the installation surface so that it becomes flat and smooth. If a gap exists and the antenna is tightly clamped, the chassis will distort and become damaged by vibration. Wrap a cloth
7ZPRR0001 8 b) Avoid using vibration-proof rubber and resin • Do not insert an elastic body, such as vibration-proof rubber or resin, between the mount base and the antenna chassis' legs. If rubber or resin is inserted, the amplitude of vibration increases, resulting in the possibility of damage to the antenna. Furthermore, if installation bolts become loose due to deterioration of rubber or resin, the antenna may be damaged or fall from its mount. 3) Installation and clamping method a) Installation direction • Installation should be done so that the cable gland side is oriented accessibility by maintenance staffs. b) Bolts, nuts and tightening torque to be used • Use stainless steel bolts for the antenna and uniformly tighten all of the bolts using double nuts for each bolt so that the antenna will not become loose (Table 2-1). • Although the length of the bolt will differ according to the thickness of the mount base, use a bolt long enough so that more than 4 millimeters of thread protrudes beyond the double nuts after the double nuts have been tightened. Table 2-1 Length of antenna mounting bolts and tightening torque Antenna Unit Thickness of Mount Base (mm) Bolt Torque (N-m) 12 M10×55(mm) SUS304 40 c) Use of washer and corrosion-resistant measures • At the location where a bolt's head or nut comes in contact with the antenna chassis' legs and the mount base, insert a plain washer which fits the bolt; and, at the location where the nut comes in contact with the plain washer, insert a spring washer, and then securely tighten the nuts (Fig.2-3). • To prevent corrosion due to the contacts between different metals, such as the antenna chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and nuts with sealant (Fig.2-3).
7ZPRR0001 9 Fig.2-3 Use of washer and corrosion-resistant measures d) Grounding and corrosion-resistant measures • Ground the antenna chassis and the installation surface (hull) by using an earth line. Apply sealant to the connection portion of the earth line to prevent corrosion and damage by vibration (Fig.2-4). Fig.2-4 Grounding and corrosion-resistant measures
