Paper Abstract

In this paper we consider the detection of small targets within an IR scene that are embedded in a dominant clutter background. A feasible approach toward addressing this issue is to invoke some form of signal processing that allows the clutter to be reduced from the scene prior to target detection. An NRLS scheme is employed which functions as whitening filter prior to matched filtering. The NRLS scheme is based on a second order truncated Volterra series expansion. The goal is to adapt to image nonstationarities and to equalize unknown system nonlinearities, prior to matched filtering. Simulation results based on both synthesized and `real world' nonstationary IR images are presented.
