频率编码脉冲是一种大时宽带宽信号，具有良好的距离分辨性能，并可拥有较窄的瞬时带宽。推导了频率编码脉冲信号与步进频率编码脉冲信号的模糊函数，分析了其距离、速度分辨性能及其相应关系，并对频率编码脉冲信号模糊函数的旁瓣抑制问题进行了讨论，结果表明，采用遗传算法得到的频率编码工程优化值，能较好解决目标距离、速度的联合测量问题。%In this paper, the relationship between the deployed number of radar in a netted radar system and its Pd has been studied. To improve Pd of a radar network, the method for deciding the deployed number of radar economically in a netted radar system and some conclusions about the netted radar system have been given.
