Abstract :
Step frequency technique has been used in high resolution SAR system widely. This paper describes the error existing in step frequency SAR system. We have some simulation according to the error forms. Amplitude and phase error has been compensated by making use of the experiment data. And it shows that the phase error between step frequency signals influences most to the imaging quality and plays a decisive role to the result of pulse compression.
