Abstract:
1. A method for displaying at least one of range and Doppler of a moving remote target, said method comprising the steps of: generating return radar signals from at least one moving target; from said return radar signals, generating a two-dimensional image by matched linear filtering, which matched linear filtering is based upon maximization of the peak amplitude of combined set of pixels of the two-dimensional image, which undesirably spreads the resulting pixels of the image in both dimensions to produce a point spread function; performing a coherent deblurring of the image including its point spread function to produce a deblurred image, by filtering with coefficients derived from a least-squares criterion wherein phase information of the signals is preserved during the coherent deblurring; and displaying at least one of range and Doppler information from said deblurred image.
