FORMATION OF MODEL DATA FOR SPACEBORNE RADAR IMAGE PROCESSING ALGORYTHMS’ TESTING

. The paper examines modern radar methods for Earth remote sensing using synthetic aperture radar (SAR) systems and their mathematical models. The software based on the mathematical model has been developed for generating test SAR raw data. The simulation takes into account the set of parameters such as pulse width and chirp rate, distance to the object, and spacecraft velocity. The modeled SAR raw data serve as input for radar image synthesis algorithms. The paper presents the examples of modeled SAR raw data and the radar images synthesized from them, which are confirming the accuracy of the modeling.
