摘要:建立了合成孔径雷达回波视频信号模型,提出了一种用AWG520任意波形发生器生成SAR回波视频信号的方法,并用这种方法模拟了SAR实时成像的回波视频信号.把这种视频信号通过A/D采样送入SAR实时处理机,用来考查SAR实时处理器连续动态成像的性能,如实时性图象拼接、多普勒中心估计、载机运动补偿及SAR前斜视成像性能等.

Abstract: The video signal model for synthetic aperture radar (SAR) is set up,and a method to generate echo signals for SAR using AWG520 arbitrary waveform generator is presented.Then,the video echo signals of real-time imaging for SAR are simulated.When these video signals are inputted to the real-time processor of SAR after sampled through A/D,the performance of continuous dynamic imaging for SAR can be examined,such as join of real-time images,doppler frequency center,moving compensation of airplane and the performance of front-slant imaging,etc.

Key words: synthetic aperture radar, AWG520 arbitrary waveform generator, video signal model
