1. A duty cycle dithering method for use with electronic support measures (ESM) and radar warning receivers that provides for improved probability of intercept at low utilization levels, comprising the steps of:

  • choosing a maximum duty cycle for the ESM system;

    allocating the chosen duty cycle to the ESM system every frame;

    at the beginning of each frame, selecting a random offset for an ESM scheduler;

    subtract the random offset from the maximum duty cycle to compute an ESM duty cycle for that frame;

    commanding the ESM system to collect data based on the computed ESM duty cycle for that frame; and

    repeating the commanding step each frame.
