Abstract

The radar-tracking images data processing has been received by a SAR with sensitivity-time control (STC) are considered. Theoretical models of underlying terrain of various types are offered. Theoretical STC functions for various operating modes SAR and types of the underlying terrain are calculated, allowing to improve the radar-tracking image at the expense of correction intensity distortions. Possibility to bring the correcting factors, considering instability of parametres of blocks on a pilot-signal is considered.

Keywords:

sensitivity-time control; scattering cross-section; farness distortion; internal calibration
