Abstract :
A computer simulation of frequency swept holography is presented. A properly scaled, divergent synthetic aperture generated by frequency sweeping a linear array of synchronous detectors is employed in imaging a rectangular object. An undistorted and edge enchanced image of the object is reconstructed and compared with earlier results. The edge enhancement effect in the image is explained.
