A General Two-Dimensional Spectrum Based on Polynomial Range Model for Medium-Earth-Orbit Synthetic Aperture Radar Signal Processing

摘要：

The kth-order polynomial range model (PRM) for Medium-Earth-Orbit (MEO) Synthetic Aperture Radar (SAR) signal processing is proposed, analyzed, and verified in this paper. The coefficients of the PRM are calculated according to the relative state vectors between the satellite and the given target on earth, which implies power series expansion around the beam center crossing time. In addition, the relevant two-dimensional spectrum is deduced out as well by using the principle of stationary phase (POSP) and the series reversion approximation. The accuracy of this spectrum is flexible and limited both by the order of the PRIM and the order of the spectrum in an expanded form. Therefore, the PRMbased spectrum is general for MEO SAR with any azimuth resolution at any orbit height
