Bistatic synthetic aperture radar (Synthetic Aperture Radar, SAR) split due transceivers , flexible configuration , in appropriate geometric layout conditions , depending on the aircraft before the region is formed Doppler line of equidistance line and nearly uniform rectangular partition , as the high-resolution imaging enabling an effective solution to the traditional SAR imaging front blind spot problem autonomous landing of aircraft , have important applications in the scene matching guidance . This thesis is to carry out the two imaging modes for solo and Flying Forward Looking SAR echo model point target response function and imaging methods , the main work includes : 1. Establish a forward-looking double-base the SAR spatial geometry model back wave model derived point response function with two-dimensional spectrum reveals a the double base forward-looking SAR big range migration and strong coupling characteristics , laid the theoretical basis for the algorithm design . Study double-base forward-looking SAR backprojection (Back Projection, BP) algorithm , to achieve a more accurate imaging of the double base before , as the SAR , while analysis of the strengths and weaknesses and the scope of application of the BP algorithm . 3 . Suitable for solo , forward-looking SAR change scale inverse Fourier transform of (Scaled Inverse Fast Fourier Transform, SIFFT) imaging algorithm to solve the system - mode range migration and strong coupling fast imaging . 4. Proposed the Flying forward looking SAR SIFFT of imaging algorithms , the algorithms to effectively solve the Flying Forward Looking SAR spectrum model complex problems fast imaging . The above algorithm by point target simulation experiments to validate .
