摘　　要：从SM-3拦截弹发射过程、探测设备、探测方向、探测时间、制导指令信号能量方面分析了弹道导弹探测SM-3拦截弹的可行性,提出了先截获SPY-1D雷达目标探测信号,然后根据信号AOA参数查找SM-3拦截弹制导指令信号的方法,分析了SPY-1D雷达目标探测信号与SM-3拦截弹制导指令信号的差异,指出了脉内调制和重频周期是区别两者的重要特征,最后指出这种信号检测方法存在的不足。Based on the analysis of SM-3 missile launch process,detecting equipment,detecting direction,detecting time,homing command signal energy,the feasibility of ballistic missile warning SM-3 missile is analyzed. And a way of detecting SM-3 missile is presented by means of intercept SPY-1D radar target detecting signal at first,and then according to the signal angle of arrive（ AOA）,SM-3missile homing command signal is checked. The difference between SPY-1D radar target detecting signal and SM-3 missile homing command signal is analyzed. It is indicated that pulse modulation and pulse recurrence interval（ PRI） are important features to distinguish them. At last,the weakness of this signal detection way is pointed out.
