Zusammenfassung:A GeoSAR satellite system ambiguity optimization method based on a dual-band reflector antenna comprises the following steps: calculating the ratio of all ambiguity point signal energy intensity to target signal energy intensity in the range direction to obtain the range ambiguity of each distribution target in an imaging range; calculating the ratio of the sum of the signal energy of each ambiguity point in the azimuth direction to the energy of the target point to obtain the azimuth ambiguity of each distributed target in the imaging range; and except for the range direction and the azimuth direction, calculating the ratio of the sum of the signal energy of each fuzzy point to the energy of the target point to obtain the cross ambiguity of each distribution target in the azimuth direction in the imaging range. The ambiguity optimization calculation method of the GeoSAR satellite is provided on the basis of the dual-band GeoSAR system design architecture, the universality is good, and the image readability o
