Imaging research of spaceborne SAR measured data based on Range Doppler algorithm
Aiming at the imaging problem of synthetic aperture radar(SAR),the Range Doppler(RD)imaging algorithm was derived based on the point target scattering model and the signal frequency spectrum analysis.The ef-fectiveness of the imaging algorithm was verified by point target SAR imaging simulation.On this basis,spaceborne SAR imaging of the measurement data of RADARSAT-1 was realized,and the comparision with the corresponding region of the satellite remote sensing map showed that the coastal contour and the shape of striking buildings of the two were basically consistent,which the effectiveness and efficiency of the RD imaging algorithm was verified in processing spaceborne SAR measured data.
