    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。

    在戰略和戰術雷達制導導彈中，一項重要的工作就是對目標的準確跟蹤，這取決于導彈雷達對目標的準確定位。為了保護雷達天線不受外界環境的影響，天線罩被應用進來，但天線罩在保護天線不受外界惡劣環境影響的同時對天線電磁輻射產生某些干擾，使天線的電氣性能降低，影響天線的功率傳輸，更重要的是產生瞄準誤差。它使目標的視在位置與真實位置有一個角度差，這個角度差就是天線罩的瞄準誤差。
