Azimuth - Elevation Estimation Performance of a Spatially Dispersive Channel.

Abstract

TN-1973-44DOT-FA72WAI-261FAA-034-241-012ESDTR-73-344*Sonar signals, *Signal processing, *Multipath transmission, *Estimates, Signal to noise ratio, Degradation, Information theory, Fourier transformation, Arrays, Spread spectrumAmbiguity functions, Most Project-2, Most Project-2A model is presented for the estimation of azimuth and elevation in a dispersive media where the signals come from a continuum of directions. These bounds depend upon the array ambiguity patterns and the channel spread function. Specific cases are discussed showing how the result reduces to an easily tractable analytical tool in many cases of interest. The model discussed is applicable to angular estimation performance in the presence of such interference as diffuse multipath, chaff clouds, vertical angle of arrival spread in sonar systems and turbulent and multiply scattered optical channels.
