Abstract
Techniques are provided for jammer detection. A methodology implementing the techniques according to an embodiment includes steering a beam in a specified direction to generate a power measurement, the specified direction selected from a plurality of directions, such that the method comprises scanning through the plurality of directions. The method also includes adaptively steering a null in the specified direction and measuring a gain of the received signal in the null direction. The method further includes calculating a difference between the power measurement and the measured gain and generating a difference-based detection that the received signal is associated with a jammer at the specified direction. The difference-based detection is based on a comparison of the power difference to a power difference threshold value. The power difference threshold value is based on a desired probability of false alarm and probability of detection, and/or desired angular resolution.
