In this paper, we presents a general target detection and processing system used specially in jammer which requires faster correspondence and reacting quickly. This target detection and processing system is based on the DSPs TMS320C6201 and can be used in various fields, e.g, radar, sonar, communication and imagine processing. This paper introduces the whole system structure, hardware platform and software system detailed. This system is realized in jammer target detection system and well effect have gotten.
