Abstract
A mathematical model of the range-gate pulloff electronic countermeasure is developed based on a statistical model for the radar return from a slowly fluctuating point target in the presence of white noise. It is shown that the same model is also appropriate for describing velocity-gate pulloff. An optimization problem is formulated which determines the jammer delay inducing the maximum bias in the range estimation processor of the victim radar. These results are then applied to the specific case in which the transmitted signal is a gaussian pulse. The optimal delay and bias are calculated as functions of the signal-to-jammer power ratio and the pulse width of the transmitted signal.
