Methodological approach to compensation of atmospheric distortion in the formation of images obtained using radars with synthesized aperture of a space-based antenna

This article considers the influence of atmospheric disturbances on the values of the signal parameters of a radar with a synthesized aperture of a space-based antenna. Significant phase disturbances of the trajectory signal in earth remote sensing systems lead to a violation of its coherent structure and can lead to complete destruction of the radar image. One of the preferred ways to solve this problem is to improve the algorithms for generating the reference function. A new methodological approach to compensation of atmospheric disturbances in the formation of images is proposed, allowing to improve the quality of radar image synthesis it is characterized by a joint account of the influence of tropospheric and ionospheric disturbances at the stage of forming the reference function. The dependences of the distance measurement error on the location angle for different levels of solar activity are obtained and the results of estimating the level of atmospheric errors based on the considered approach are presented.
