Abstract
We investigate the performance of a modified fringe-adjusted joint tra nsform correlator for detecting multiple targets present in an input s cene. This technique, involving adjustment of the joint power spectrum (JPS) on the basis of the input-scene-only power spectrum, and apodiz ation of the modified JPS on the basis of the reference signal power s pectrum, is found to yield good correlation output. Simulation results are presented to verify the performance of the proposed technique.
