Abstract

The invention provides a space-borne synthetic aperture radar ground range resolution representation and parameter design method. According to the method, synthetic aperture time and an emission signal bandwidth can be designed by representation of a long axis ground range resolution rho l and a short axis ground range resolution rho s of an acquired space-borne synthetic aperture radar according to resolution l needed by the radar, and radar related parameters are adjusted, so that the adjusted radar resolution is smaller than or equal to the l. The method overcomes the shortcoming that the ground range resolution is represented by azimuth and range direction ground range resolution, the ground range resolution capacity of the SAR (synthetic aperture radar) can be more comprehensively reflected, and the resolution in all directions of a ground range plane meets system index requirements.

Description

technical field

[0001] The invention belongs to the technical field of synthetic aperture radar, in particular to a spaceborne synthetic aperture radar ground range resolution characterization and parameter design method. Background technique

[0002] Synthetic Aperture Radar (SAR) is an all-weather, all-weather high-resolution microwave remote sensing imaging radar that can be installed on aircraft, satellites, spacecraft and other flying platforms. It has unique advantages in environmental monitoring, ocean observation, resource exploration, crop yield estimation, surveying and mapping, and military applications, and can play a role that other remote sensing methods are difficult to play.

[0003] Space-borne synthetic aperture radar refers to the synthetic aperture radar with satellite as the carrier. Spaceborne SAR can operate in circular or elliptical orbits. In a circular orbit, the velocity direction of the satellite's Earth-centered Earth-fixed (ECEF) coordinate sy...
