Inverse filtering in the presence of Doppler with application to specular multipath parameter estimation

It has been shown previously that, using a deconvolution method such as projection onto convex sets (POCS), which relies on some form of inverse filtering, one can increase the resolution of multipath parameter estimation in a Doppler environment beyond that which is achievable using correlation processing alone. This paper shows that the output of an inverse filter in the presence of Doppler can be characterized by two signal-related functions: one of which is free from the range-Doppler coupling effects inherent in correlation processing.
