Abstract: The signal Processing system (SPS) is the core of low altitude navigation pop system, The SPS is a sort of tightly coupled system by TMS320C320 DSP. It accomplished measure distance, measure angle. echo processing, infrared imagery processing, servo control and communication with bus system of aviation electron and so on of ground following radar, finished functions of ground following and ability of infrared sight at night when airplane flying in super low-altitude. The paper introduces in detail system structure of SPS and signal processing module.
