混沌动力学作为研究非线性系统的一种新方法已引起雷达界的重视,混沌信号是一种类随机性信号,具有极强的抗干扰性和极低的截获概率。研究了混沌在雷达中的应用,分析了混沌理论在雷达波形设计、信号检测与估计、目标识别、及杂波分析与建模等领域内的发展情况,指出在雷达应用技术中引入混沌理论是雷达技术发展的必然趋势,并预测了混沌理论与雷达技术研究发展的前景。

Chaos theory,as a new way in nonlinear system research recently,has been paid more attention to by the radar researchers all over the world.Chaos signal is a pseudo random signal,which has high anti-jamming ability and low intercept probability.Status of chaos theory applied in radar systems is studied,the developments of chaos theory in radar wave forms generation,signal detection and estimation,target recognition,and radar clutter modulation is analyzed in this paper.Applying chaos theory into radar system is the result of the development of radar technologies,and its future is prospected.
