摘要
为了获得高距离分辨率,将线性调频信号作为子脉冲构成调频步进雷达信号。文中对该体制雷达的波形参数设计进行了理论分析,以及目标运动的多普勒效应对这种信号的影响。最后针对某型号雷达,给出了计算机仿真结果。
In order to obtain high range resolution, the Chirp signal is used as subpulse to form stepped frequency modulated radar signal. In this paper, the waveform parameter design, signal processing, Doppler effect caused by target motion and pulse compression are analyzed theoretically. Lastly the result of computer simulation compared with a certain type of radar is given.
