Effects of Atmospheric Turbulence on High Resolution SAR Performance

Abstract:

The phase errors of radar signals can be caused by random tropospheric refractivity fluctuations in a turbulent region, which affects the imaging performance of high resolution airborne SAR. A detailed simulation approach is presented to estimate the phase errors caused by atmospheric turbulence. Applying the von Karman spectrum as the model for turbulent refractivity fluctuations and the raw data collected by a Ku-band airborne spotlight-mode SAR with 0.1m resolution, we simulate the results of effects of atmospheric turbulence on SAR image focusing.
