This application relates to a method for selecting sources of illumination to jam, performed by an apparatus of selecting sources of illumination to jam for passive radar jamming. The method may include, predicting sources of illumination used by a virtual passive radar of interest disposed within a jamming range with respect to the location of a passive radar jammer. The method may also include selecting sources of illumination as candidates for jamming if the signal strength of a target reflection signal received by the virtual passive radar of interest from the sources of illumination is equal to or greater than an acceptable received signal strength. The method may further include picking out which sources of illumination to jam from the sources of illumination selected as candidates for jamming, based on how frequently the virtual passive radar of interest uses each of the selected candidates for jamming.

This application relates to a passive coherent location (PCL) system. In one aspect, the PCL system includes a signal measurement device configured to receive a plurality of signals from a plurality of illuminators and generate an In-phase signal and a Quadrature signal corresponding to each illuminator using the received signals. The PCL system also includes a signal processing device configured to detect a first target using the In-phase and Quadrature signals and measure a bistatic range of the first target and a bistatic velocity of the first target to generate a plurality of pieces of line track information corresponding to the first target. The PCL system further includes a locating device configured to generate target track information of the first target using the line track information and predict a position vector and a velocity vector of the first target using the target track information.
