Target Detection with a Direct-Reception Optical Radar.

Abstract

A theoretical study of the use of a direct reception Nd: YAG laser radar for target detection is reported. This work builds from a mathematical system model which incorporates the statistical effects of propagation through atmospheric turbulence, target speckle and glint, and receiver noise; both photomultiplier and avalanche photodiode receivers are considered. Results are presented for the receiver signal-to-noise ratio which show, explicitly, the deleterious effects of atmospheric scintillation on system performance. The structure and performance of the optimum likelihood-ratio processor for single-pulse target detection are analyzed. (Author)
