| Abstract: | In traditional methods for calculating ground clutters, the ground is always partitioned by "range-doppler" curves. Based on sending-receiving theory of radar aetenna and radar target scattering theory, the clutter power spectrum density (PSD) computation formula for synthetic aperture radar (SAR) has been derived in detail, furthermore the close-form integral solution and the real-time arithemetic for the formula are also discussed. |
