Abstract

Using real data from infrared imaging systems, we have designed a generalized matched filter to recognize tank images viewed from many different angles. Performance parameters of the GMF as a function of input rotation angle are presented. Amplitude and phase GMFs are progressively phase biased in order to better understand the tradeoff in performance between discrimination capability and light efficiency. An unexpected and encouraging result is that phase-only GMFs exhibit high figures in both performance categories.
