■[Mission]-The GD-200X Manpack Ground Surveillance Radar detects ground targets (including tank, armored fighting vehicles, personnel) and measures coordinates (range, azimuth) in any season, including poor visibility conditions. Manpack Surveillance and Target Acquisition Radar is a highly versatile low-power, high-performance ground surveillance radar. The Manpack radar provides wide-area surveillance to a maximum range of 1000m, day or night and in all weather conditions. This system can be carried by only one persons, and put into action in less than 3 minutes. This radar can be installed at army barracks, police checkpoints for surveillance and operation, border control as well as schools for security and protection. ■[Concept of Operation]-Targets are classified automatically using target classification in terms of Doppler effectiveness, with output Doppler return being channeled to the operator. ■[Operating Principle]-The radar detects and tracks several kinds of ground targets including a crawling person as well as vehicles in a high probability with a sophisticated device and signal processing technology such as LFM impulse compress, range side removing, frequency-agile, FFT filter group process, solid transmit technology. The target reflection signal into the antenna is input to RF front–end with SAW filter through the circulator. The target signal of intermediate frequency mixed with the local oscillation signal that comes from the local oscillation unit through the SAW filter and the limited amplifier. The digital target signal converted in the signal processing unit is processed, so the final target information (range, azimuth) is obtained. On the display, an operator simultaneously tracks the locus of several targets. And it identifies the kind of selected targets.
