合成孔径雷达(SyntheticApertureRadar)是一种新型高分辨力成像雷达。其在距离上利用发射的线性调频(LFM)的脉冲压缩信号来获取距离上的高分辨力,在方位上利用接收脉冲之间的多普勒信息获得方位上的高分辨力。本文在简单分析合成孔径雷达工作原理基础上,针对合成孔径雷达的特点与弱点,讨论了几种干扰样式。
Synthetic Aperture Radar (SyntheticApertureRadar) is a new type of high resolution imaging radar. It uses the transmitted LFM pulse compression signal to obtain the high resolution in range and uses the Doppler information between received pulses in azimuth to obtain the high resolution in azimuth. Based on the simple analysis of the working principle of Synthetic Aperture Radar (SAR), this paper discusses the characteristics and weaknesses of Synthetic Aperture Radar (SAR) and discusses several interference patterns.
