Abstract: Random beam positioning for an E-scan radar system having an electronically teerable antenna is controlled by a digital computer which is programmed to generate lists or files of portions of the desired area of surveillance. Two separate lists are generated corresponding to the forward and rear postions of the area of coverage. These lists are thereafter independently randomized and combined to generate beam position commands for the desired surveillance region, thereby providing full radar coverage over a desired region while decreasing the probability of being tracked by an undesired detector.
