Improved Range Resolution Filters for Rectangular-Pulse Radar Systems
Evans RJ., Fortmann TE.
The performance of several new clutter-reduction filters suitable for rectangular-pulse radar systems is investigated. The new filters consist of various approximations and modifications of two filters known to be optimal for certain criteria: the well-known Urkowitz filter which optimizes the clutter improvement ratio, and the newer sidelobe reduction filter which minimizes output noise power subject to peak sidelobe constraints. The new filters are compared using five basic criteria: clutter improvement ratio, signal-to-noise ratio, sidelobe peak ratio, pulse compression ratio, and filter complexity. The results are summarized in tabular and graphical form. Copyright © 1980 by The Institute of Electrical and Electronics Engineers, Inc.
