摘　　要：分布式检测系统可以提供更高的信噪比,提高系统在复杂电磁环境下的生存能力,抗干扰能力。由于OSCA-CFAR检测器具有较好的抗干扰性能,因此,在此研究了分布式OSCA-CFAR检测系统采用"AND","OR"融合准则时在非均匀背景下的检测性能。分析表明,分布式OSCA-CFAR检测系统采用"OR"融合准则时在非均匀背景下具有更好的抗干扰性能。The distributed detection system can provide higher signal to noise rate （SNR）, and improve the viability and anti-jamming ability in complicated magnetoelectric environment. OSCA-CFAR detector has better anti-jamming performance. The detecting performance of distributed OSCA--CFAR detection systems as adopting ＂AND＂ and ＂OR＂ fuse rule in the non- uniform background is researchd. The analysis indicates that the distributed OSCA-CFAR detection system has better anti- jamming performance when it adopts ＂OR＂ fuse rule in the non-uniform background.
