Sensor Modulation Effects upon Laser Signatures.

Abstract : This study is an analysis of coherent sensor system observable effects which tend to obscure target properties of interest. The main effects studied are finite system resolution, speckle, shot noise, and atmospheric propagation. In addition to these effects, several scenarios were considered to provide realistic assessments of their effects on the performance of laser radar systems. Also included is an investigation of the feasibility of performing range-Doppler imaging using different lasers in the measurement of range and Doppler. The analysis was made to determine the existence and extent of any fundamental problem areas which would prohibit or seriously limit the use of this technique. (Author)
