Complex of algorithms for fast determination of the parameters of motion of high-speed vessels in the digital signal processing system of a space synthetic aperture radar

Abstract

The article presents the main considerations for determining the tangential velocity of high-speed vessels in the digital signal processing system of a space synthetic aperture radar with an amplitude-phase program discriminator in the azimuth channel. The article suggests a complex of algorithms for fast determination of the parameters of motion of high-speed vessels in the digital signal processing system of a space synthetic aperture radar. The article contains the results of semi-natural experiments that confirm the reliability of the algorithms and their effectiveness in solving the problem of observing the sea surface.
