ABSTRACT:
A duty dithering method for use with electronic support measures and radar warning receivers, and the like, that provides for improved probability of intercept at low utilization levels. The electronic support measures (ESM) system and radar warning receiver are controlled by a multi-system sensor manager having an ESM scheduler. In accordance with the present method, a maximum duty cycle is chosen for the ESM system. The chosen duty cycle is allocated to the ESM system each frame by the ESM scheduler. At the beginning of each frame, the ESM scheduler picks a random offset and subtracts it from the maximum duty to compute an ESM duty for that frame. The ESM scheduler commands data collections based on the computed duty for that frame. This step is repeated each frame.
