| 摘 要： | 针对以电视伴音信号为照射源的外辐射源雷达在长时间积累时,距离和多普勒频率徙动对目标探测的影响,定义了一种时延-频移-时延率-调频率联合模糊函数,推导了电视伴音信号的平均联合模糊函数与积累增益损失因子,给出了积累增益损失与目标运动速度、加速度和积累时间的关系以及相关结论,为分析外辐射源雷达的探测性能提供了一定的理论参考.

| Abstract: | The performance of target detection using long-time integration would be influenced by the migrations of range and doppler frequency.In order to analyze the influence in the external illuminating radar which makes use of TV radio signal,an associated ambiguity function expressed by the time delay,doppler shift,time delay varying rate and chirp rate is defined.Subsequently,the average associated ambiguity function and integration loss of the TV radio signal are both derived.The relationship of the integratio... |
