MOVING TARGET IMAGING AND TRAJECTORY COMPUTATION USING ISAR

Novel algorithms for moving target imaging and trajectory computation using a two-receiver radar are presented. The range-bin alignment is i mplemented with an adaptive method using the envelope correlation feat ure of different returns and the angular trajectory equation is solved using a linear least squares method combined with a unique phase-unwr apping technique. The angular positions of the synthetic array element s are determined from the trajectory computation. Three target models moving along a perturbed straight tine are used to verify the proposed algorithms.
