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.
多髮多收雷達(MIMO),最近在新型雷達中談論較多,它具有多髮多收的能力,既有好的抗榦擾性能,又有較好的髮現隱身飛機能力等.由于隻看到一些材料或文章,沒有看到實際的設備,因此對MIMO雷達隻能做一些榦擾構想.文章從對抗的角度齣髮,把各種雷達分為不同類型,併指齣它們共同的弱點,MIMO雷達也不例外,也是可以被榦擾的.文中提齣瞭MIMO雷達的組成構想示意圖,列齣瞭它可以利用多頻段和目標特性髮現隱身飛機的能力.舉例分析瞭自衛榦擾機對MIMO雷達榦擾方程、榦擾所需的等效功率;分析瞭掩護式榦擾機對MIMO雷達的榦擾方程、所需的榦擾等效功率,併繪製瞭對MIMO雷達的榦擾機原理框圖,指齣對MIMO雷達榦擾繫統研製的難度等.

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 poimed out.Therefore,unexceptional MIMO radar can be jammed too.In this paper,MIMO radar composition is illustrated,how to detect stealthy aircrafts by using multiple frequencies and target characteristics is described,interference equation of protective jammer on MIMO radar and equivalent power necessary for interference are exampled.Besides,interference equation of covering jammer on MIMO radar and equivalent power necessary for interference are analyzed.Principal diagram of MIMO radar jammer is presented and technical difficulties in MIMO radar jammer system development are concluded.
