摘要
针对利用机会照射源的无源探测系统,论述了一种新的机会照射源——CDMA基站信号,利用CDMA基站的下行信号为照射源构成无源探测系统,分析了CDMA信号的构成形式及特点,分析了利用民用CDMA蜂窝移动通信网络实现对空中动目标探测的技术可行性,并对探测距离进行了估算。
Passive bistatic （multistatic） radars using illuminators of opportunity have attracted much attention recently. A new illuminator--CDMA signal is discussed. The downlink signals from the CDMA base station are used as the illuminators of opportunity in the passive detective system. The analysis of the waveform and character of CDMA signal and the feasibility of this detection system are given in detail. At last, the detective range is estimated.
