Abstract

Multifunction laser radar systems can collect two-dimensional target images of intensity, range, or velocity, and many such systems augment their active-sensor channel with a FLIR channel. This paper addresses the problem of optimal target detection using such an active-passive sensor, focusing on the performance benefits that accrue when multidimensional data-active-sensor range, velocity, and intensity, plus passive-sensor intensity - are combined in the detection processor. Generalized likelihood ratio tests are derived for active-passive detection processing, and quantitative performance results - receiver operating characteristics - are obtained through computer simulation of pixel-level statistics. The performance predictions for the gamut of multidimensional, multipixel detection processors are confirmed via experiments performed using a multidimensional laser radar test bed.
