A high-resolution spaceborne SAR wave potential design method for large scene

Abstract

For high resolution spaceborne SAR, high resolution needs large rotation of azimuthal angle, so range cell migration is larger. In order to solve this problem, this paper proposes a design method of wave location for high resolution spaceborne SAR. During the working process, the echo receiving window is sliding by changing system repeat frequency, so the echo of scene can be received completely. This method includes two kinds of wave level design: piecewise variable repetition frequency and group variable repetition frequency. The method can meet different scene application. The method is simple, reliable and practical. It can be widely used in high resolution spaceborne SAR.
