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.
