Real time processing of a Lattice Wave Digital matched filter

Abstract

Based on the theory of wave digital filters (WDFs), an algorithm to represent a single pulse matched filter for radar applications is described. This matched filter is obtained by calculating the coefficients of a Lattice Wave Digital Filter (LWDF) adaptors by getting the filter transfer function that results from the arbitrary amplitude transfer function method. In this paper, we are interested only in the main loop of the matched filter frequency response and its pass-band edges locations. The design methodology permits the realization of the system for real-time applications.
