Study on Digital Signal Processor of the High Resolution Middle and Long Range Laser Ranger

PING Qingwei1,HE Peikun1,ZHAO Baojun1, ZHANG Zhengyu2, LI Songshan2 (1.Department of Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China;2.North China Reseach Institnte of EO, Beijing 100015, China)  
In the paper a digital signal processor of narrow laser echo pulse based on 500MHz ADC is designed. It solves the technological dificulty of high speed ADC.High speed DSP(TMS320C6XXX)chip is used for processing data, which supply the hardware tool for CFAR Detecting, target matching, signals accumulation and so on. At present, this processor had been used in practice. By the measure, the performance of the laser ranger with high speed ADC and high speed data signals processing is remarkably improved. Its minimum detecting signalsnoise is 3 and increased triple.
