摘要
以基于GSM的无源雷达系统为背景 ,研究了GSM信号的模糊函数 ,特别是针对GSM信号的调制特点 ,采用MSK代替GMSK调制的近似分析方法得到了一种时延和频移向模糊函数的解析表达式 ,为现有GSM信号作为雷达信号在目标检测。
In the analysis of passive radar using GSM signal as illuminator of opportunity, the Ambiguity function of GSM signal is investigated. In order to obtain an analytical expression of time delay and Doppler-shifted ambiguity function, We analyze the modulation feature of GSM signal, and adopt an approximate method of substituting GMSK with MSK modulation. The results may provide some theoretical reference for detection, estimation and clutter cancellation of GSM passive radar.
