DSP在雷达目标自动检测录取系统上的应用

介绍了一种新的目标自动检测录取系统。它采用数字信号处理芯片（DSPC）和高速现场可编程（FPGA）芯片组成硬件系统，充分利用了雷达回波信息，利用能量加权法精确计算目标方位中心，有效抑制目标分裂。文中还就某现役雷达给出一种目标自动检测的硬件实现方法，分析了实时处理速度。该系统满足了搜索雷达高精度、多批次、实时探测目标的要求，具有体积小、可靠性高，适应性强的优点。

Application of DSP in Automatic Radar Target Detection and Extraction System

A new method for realizing an automatic detection and extraction system is presented. The digital signal processing (DSP) and the field programmable array (FPGA) chips are used to form the hardware system. The information of the radar echo is fully used. An energy weighting method is employed to precisely locate the targets and efficiently avoid the split of target. A method for hardware realization using DSP for a searching radar in active service is described and the speed for real time process is estimated. This system meets the requirements of high resolution searching radar to precisely detect multi batch targets in real time and has the advantages of small size, high reliability and general compatibility. It can be widely used in radar engineering.
