Abstract

This paper provides analytic expressions for the performance of optimal matched filters designed to utilize spatial, temporal, and spectral observations of point targets against cluttered backgrounds. The analysis explicitly treats the situation of bipolar low contrast target signatures typical in advanced infrared systems such as the infrared search and track systems. In these cases, one must include the temporal effects due to target motion across the cluttered background and can not assume that the target signature is simply additive. The analysis also provides explicit expressions for the effects of frame-to-frame registration errors that impact the temporal performance of the filter. The analytic expressions are given in a four- dimensional Fourier transform setting which provides a concise and easily manipulated format.
