Missing Pulse Clutter Processing

Abstract

Missing pulses resulting from RFI blanking, ambiguous range returns when no filter pulses are used, or eclipsing can seriously degrade conventional clutter filters. This report investigates the effects of a missing pulse on uncompensated and optimum clutter filters. The maximum improvement factor method of Emerson and other methods are compared to the optimum filtering. New methods and results using a minimax log energy search method are described and are shown to provide performance and/or implementation complexity advantages. Keywords: Interference, Matched filtering, Clutter processing, Radar signals; Signal processing, Filter design.
