ABSTRACT:
A method for displaying information relating to the range and Doppler of a remote target includes transmitting electromagnetic energy toward the target, and receiving reflected signals defining a two-dimensional (range-Doppler) radar image. The reflected signals are matched-filtered, which tends to blur the image. The image is deblurred while the features of thermal noise enhancement and irregularity of the deconvolved output are constrained to produce a single point deblurring output.
