摘要
多输入多输出雷达采用了空间分集和频率分集技术,有效地克服了由于雷达截面积角闪烁带来的性能损失。文中介绍了MIMO雷达的工作原理,分析了对MIMO雷达有效干扰的两种方式:假目标欺骗干扰和分布式干扰,并对假目标欺骗干扰效果进行了仿真。仿真结果表明,只有对MIMO雷达中的所有雷达都进行干扰时,才能对MIMO雷达系统实现有效干扰。
The multi-input multi-output radar adopts the space diversity and frequency diversity technologies, ef- fectively overcomes the performance loss resulting from the angle glint of radar cross section. This paper describes the working principles of the MIMO radar, analyzes two effective jamming modes to the MIMO radar： false target deception jamming and distributed jamming, and simulates the effects of the false target deception jamming. Simulation indicates that effective jamming is achieved only if all the radars in the MIMO radar are jammed at the same time.
