Synthesis of earth surface radar images received in “Severyanin” spaceborne radar system

The possibilities of the synthesis and use of the earth surface images obtained using space-based radar are considered. The main problem solved by radar is information support navigation of ships along the Northern Sea Route. Scheme sensing, device on-board antenna and trajectory parameters of the spacecraft are analyzed. Spaceborne radar set to the radiation phase-shift keyed signal. Navigation support radar data and timing of radar data problems have been solved. Examples and characteristics of real images are represented. Basic calculations performed in the synthesis of radar data are described. Earth probing radar is now considered a promising way to diagnose the environment.
