This paper presents a near-field 3-D synthetic aperture radar (SAR) imaging algorithm. This algorithm is an extension of the 2-D range migration algorithm (RMA). The presented formulation is justified by using the method of the stationary phase (MSP). Implementation aspects including the ...
Bistatic SAR experimental data imaging results. It should be pointed out that, since the conventional wavenumber domain algorithm realizes migration correction and slow-time compression at the same time, it is difficult to embed the second-order motion compensation effectively. Therefore the extended ...
