Embodiment Construction
[0035] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0036] The invention discloses an embodiment of a space target parameter inversion method based on the variation characteristics of a small-angle radar cross section (RCS, Radar Cross Section). In this embodiment, a certain satellite target is taken as an example. The body size of the satellite target is 1.2 meters, and it is assumed that the orbit of the satellite target is circular, and the orbit of the detector is oblate ellipsoid.
[0037] Such as figure 1 As shown, the space target parameter inversion method includes the following steps:
[0038] Step 1. Calculate and obtain the observation angle according to the space target (i.e. satellite target) and the space orbit position of the detector size change curve.
[0039] Observation angle The size of can generally be calculated from the orbital positions of space objects and detectors...
