TECHNICAL DOCUMENTATION PROTECTING PEOPLE AND ASSETS® DATE: 27 MARCH 2017 | VERSION: 1.8 30 RANGER®-X5 RADAR SYSTEM (MOBILE) FUNCTIONAL OVERVIEW AND THEORY OF OPERATION EEC® | COMPANY PROPRIETARY 2.1. Pedestal Assembly (Unit 2 A1) The design of the pedestal system for the Ranger-X5 utilizes components and elements that allow for constant outdoor exposure and 24/7 unattended operation. Utilizing multiple O-ring seals and weather tight compartments prevents contaminants from entering the pedestal from the outside environment. The motor drives used in both azimuth and elevation utilize a wave generator and circular spine, eliminating traditional gearing found in most pedestal systems. There is no traditional bull-gear and pinion, as the motor drive itself is the rotation axis. Since the motor drives are sealed and permanently lubricated, there is no periodic maintenance required. Additionally, this technology also eliminates backlash and the need to adjust backlash, and provides exceptionally high positional accuracy and repeatability. The remaining bearings utilized (elevation idler side, and drive tube stabilizer) in the Ranger-X5 are also permanently sealed and require no maintenance. A sealed slip ring limits the need for periodic or preventative maintenance. The slip ring is design is originally for high-speed operation and has a proven pedigree in military and aviation applications. Even at the highest rotation speed of the Ranger-X5 for weather operation, the slip ring operates at less than 25% of its rotational speed capacity. Figure 19. Pedestal Unit (135885-100)

Regeneration Clamp (Unit 2 A1 A2 A5) As with most servo systems, a clamp circuit is required to limit increase power supply buss voltage when the motor is decelerating under load. This common name for this process is “regeneration” and happens when the load on the unit drives the DC motor. During regeneration, the DC motor can produce enough voltage to exceed the “input” power supply voltage. More sophisticated servo amplifiers deal with this by channeling the increased motor voltage back to the source power supply. If the voltage is not “clamped” to a safe level, it can destroy or severely damage the amplifier. The servo amplifier and controller are the types that channel the increasing voltage back to the input power supply. A simple capacitor isn’t large enough to handle the power that generates back into the controller when the system is under inertial load. The Regeneration Clamp is us sufficient capacity to track the input power and ensure the servo amplifier voltage will not exceed the capacity rating. Figure 29. Regeneration Clamp (1000-327)

Payload Support Assembly (Unit 2 A1 A3) The Payload Support Assembly (Unit 2 A1 A3) houses the entire transmitter and receiver system in the Plenum Assembly (Unit 2 A1 A3 A1), the Transceiver Assemblies – Horizontal (Unit 2 A1 A3 A2) and Vertical (Unit 2 A1 A3 A3), and the Fluid Pump Assembly (Unit 2 A1 A3 A4). Figure 30. Payload Support Assembly (135953-100) 2.1.4.1. Plenum Assembly (Unit 2 A1 A3 A1) The Plenum Assembly (aka the Saddle) houses the IQ2 IFD, the I/O Control Modules, the Cold Plate, the 8-Port Ethernet Switch, and the Peltier Temperature Controllers for the Cold Plate and the Fluid Pump Assembly. Figure 31. Plenum Assembly (135540-100) 2.1.4.1.1. IQ2 Intermediate Frequency Digitizer Assembly (Unit 2 A1 A3 A1 A1) The IQ2-IFD receives the horizontal and vertical receive IF from the Horizontal UDC (Unit 2 A1 A3 A2 A2) and Vertical UDC (Unit 2 A1 A3 A3 A2). The IQ2-IFD digitizes the received IF and outputs “I and Q” serial data in digital format. The data output connects to the IQ2-DSP via a fiber-optic cable and the fiber-optic rotary joint. The IQ2-IFD Assembly (see Error! Reference source not found.) extracts the maximum amount of useable information from reflected radar energy. There are five 60 MHz IF channels sampled at >76 MHz. Four of the IQ2-IFD 60 MHz IF channels (two channels for the horizontally polarized signal and two channels for the vertically polarized signal in dual polarization systems) include wide-band down-converters to base-band for Receiver use. The fifth IF channel normally functions as a Transmitter sample (IF burst) channel for Transmitter amplitude and phase correction on a pulse-by-pulse basis.
