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
