| 摘 要： | 星载多发多收合成孔径雷达(MIMO-SAR)可以解决方位向高分辨率和大测绘带的矛盾;同时,混沌二相编码(CBPC)信号具有类似随机信号的特点以及良好的自相关和互相关特性;两者都具有良好的应用前景。将CBPC波形应用到MIMO-SAR系统中,在实现高分辨大测绘带成像的基础上可进一步降低雷达信号被敌方分析截获的概率,提高雷达系统的抗干扰性能。仿真实验验证了此方法在抗数字储频式欺骗干扰中的有效性。

| Abstract: | Spaceborne multiple-input multiple-output synthetic aperture radar(MIMO-SAR) can resolve the conflict between high azimuth resolution and wide swath.And chaotic binary-phase coded(CBPC) signal has almost the same characteristic as stochastic signal and has good autocorrelation property.They both have good prospects in future.CBPC waveform is adopted in the emitting signal of MIMO-SAR,which can not only achieve wide swath and high resolution but also improve the antijamming ability of radar system,and reduce the probability of being intercepted.At last,the validity of the method is verified by simulation examples. |
