摘　　要：本文将更通用的Rician目标模型引入MIMO雷达,并根据检验统计量的特点将目标分成三类。分析和仿真结果表明,MIMO雷达对较小k值时的Rician目标,球形目标和Rayleigh目标的检测性能比较接近,对较大k值的Rician目标检测性能优于Rayleigh目标和球形目标,而且k值越大检测性能越好。仿真结果为MIMO雷达的系统设计提供了一定的理论基础。The Rician target model that is more general is introduced to the MIMO radar,and then the targets are divided to three different kinds based on their optimal detector.The analysis and simulation show that the detection performance of MIMO radar to the Rician targets whose k is lower,the Raleigh targets and the SWV targets is nearly the same;whereas it is better to the Rician targets whose k is higher than the Raleigh targets and the SWV targets,and that the higher the k is,the better the detection performance is.The results are very significant to the design of MIMO Radar.
