  8. Advantages, disadvantages and limits of arm are thoroughly examined using signal processing methods. based on the above, incoherent and coherent two - point - source decoy methods and modified coherent two - point - source decoy methods to deflect arm are brought forward. arm ’ s homing heads are generally of mono - pulse structure, so coherent two - point - source ’ s interference resembles that to mono - pulse radar except that interference to radar belongs to far field scope, but interference to arm varies from far field to near field because relative distance drastically changes between the homing head and the two - point - source with missile ’ s homing head continually approaching the target

    Arm的導引頭一般為單脈沖體制，因此，相干兩點源對導引頭的干擾類同於對單脈沖雷達的干擾，不同的是:對雷達的干擾都是遠場，而導引頭隨著導彈不斷接近目標，兩點源與導引頭的相對位置發生劇烈變化，由遠場變化到近場;導引頭天線口面上的合成場也發生了大的變化，相位波前的畸變產生干擾，這就是相干兩點源誘偏的基本思想。
