QUANTITATIVE METHODS OF EVALUATING THE MOBILE SATELLITE COMMUNICATIONS TERMINAL ACQUISITION PROBLEM.
Abstract
A quantitative method of analyzing the tactical satellite communications terminal acquisition problem is developed in this report. In the tactical situation, the terminal's location is postulated to be anywhere about a previously estimated deployment point. Uncertainties may exist in the terminal's bearing to true North, and the terminal's horizon plane as well as location. This situation was subjected to a two-step analysis: (1) detection probability was determined as a function of antenna pattern; the resulting data was used for the generation of a search pattern, and (2) azimuth-elevation error pairs were obtained by a Monte Carlo simulation of the latitude, longitude, local North, and local horizon errors. The search pattern was displaced by the azimuth-elevation error from the satellite's assumed location; the search pattern was then executed and the time to intercept the satellite location was measured. The analysis illustrates the determination of detection probability, the construction of search patterns, the effect of antenna slewing rate on the detection probability, the determination of the sample variance and the sample mean of the acquisition time, and the effect of operator practice on the mean acquisition time.
