摘要
线性调频(LFM)信号是雷达信号处理系统中应用较为广泛的大时宽带宽积信号。针对线性调频信号进行了时频特性分析,然后运用模糊函数对该信号的性能进行分析,得出该信号具有良好的距离分辨率和速度分辨率,最后对线性调频信号的脉冲压缩过程和结果进行了讨论,并得到了雷达目标回波信号经过脉冲压缩后的仿真结果。
The LFM signal used in the radar signal processing system has large product of time width and band width. It introduces characteristic of LFM signal for time-frequency field, and characteristic of LFM signal is analyzed by using Ambiguity function. It shows that LFM signal can provide favorable range resolution and velocity resolution. Finally, the results and processes of pulse compression of LFM signal are discussed, and simulation resuhs are provided after pulse compression of radar echo of targets.
