低空导航吊舱信号处理系统设计

信号处理系统是低空导舱的核心系统，该系统是一个由ＴＩ公司ＴＭＳ３２０Ｃ３０ＤＳＰ构成的紧耦合系统，完成地面跟随雷达的测距、测角、回收重点２，红外图象处理，伺县控制和与飞机航空电子 线系统通信等任务，实现了飞机超低空飞行中地形跟随功能和红外夜视能力。详细介绍导航吊舱信号处理系统的系统结构和有关信号处理模块的设计。

The Design of Signal Processing System of Low Altitude Navigation Pop

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.
