Research of electronic compensation methods of reserence signal in the surveillance channel of semi-active coherent bistatic DVB-T2 radar

Abstract

This paper provides an overview of different electronic compensation methods of a reference signal. An algorithm for electronic compensation of the DVB-T2 direct signal in a semi-active coherent radar has been proposed. A filter that provides direct signal suppression of at least 50 dB has been developed. The results of experimental studies on the detection of low-speed target with low effective scattering surface in the presence of a powerful reference signal have been presented.
