Study on Adaptive Digital Beamforming for Spaceborne SAR Based on Capon Spatial Spectrum Estimation
In rough mountainous areas, beam-pointing mismatch problems always arise when a spaceborne Synthetic Aperture Radar (SAR) uses the traditional Digital BeamForming (DBF) approach in elevation to receive echoes, leading to the degradation of the receiver’s gain and system Signal-to-Noise Ratio (SNR)....
