Abstract

Since the time and energy of phased array radars are under great demand in modern combat systems, methods that conserve those resources are very important. Two opportunities for conserving radar resources that have not been fully exploited when tracking closely-spaced objects with currently deployed systems are revisit time selection (i.e., time to make a measurement) and beam boresight placement. While these two functions are somewhat coupled, this paper addresses only the problem of beam pointing. Previously, a methodology for track management for phased array radars hinged on the concept of organizing tracks into, so called, dwell groups that included closely-spaced targets that could be illuminated with a single beam. Pointing angle for a dwell group was determined using a geometry-based approach. While the geometry-based approach was useful in improving the entire track management function, it was known to be sub-optimal in that the detection characteristics of the targets were not considered. This paper addresses an improved methodology for assigning membership in dwell groups and selecting dwell pointing angles.
