多发多收雷达(MIMO),最近在新型雷达中谈论较多,它具有多发多收的能力,既有好的抗干扰性能,又有较好的发现隐身飞机能力等.由于只看到一些材料或文章,没有看到实际的设备,因此对MIMO雷达只能做一些干扰构想.文章从对抗的角度出发,把各种雷达分为不同类型,并指出它们共同的弱点,MIMO雷达也不例外,也是可以被干扰的.文中提出了MIMO雷达的组成构想示意图,列出了它可以利用多频段和目标特性发现隐身飞机的能力.举例分析了自卫干扰机对MIMO雷达干扰方程、干扰所需的等效功率;分析了掩护式干扰机对MIMO雷达的干扰方程、所需的干扰等效功率,并绘制了对MIMO雷达的干扰机原理框图,指出对MIMO雷达干扰系统研制的难度等.

[Abstract]
MIMO radar is a new concept featuring multiple-input and multiple-output function,great anti-jamming and stealthy aircraft detection capability.Only a few documents or articles are presented and no practical devices exist,so MIMO radar countermeasures are just conceived.In this paper,radar is categorized into various types,and their common weaknesses are pointed out.Therefore,unexceptional MIMO radar can be jammed too.In this paper,MIMO radar composition is illustrated,how to detect stealthy aircrafts by us...
