1. A method of selecting sources of illumination to jam, performed by an apparatus of selecting sources of illumination to jam for passive radar jamming, the method comprising:
predicting sources of illumination used by a virtual passive radar of interest which is disposed within a jamming range with respect to the location of a passive radar jammer, based on the location of the virtual passive radar of interest and the locations of the sources of illumination and output information thereof;
selecting sources of illumination as candidates for jamming in response to the signal strength of a target reflection signal received by the virtual passive radar of interest from the sources of illumination being equal to or greater than an acceptable received signal strength, based on the information on predicted sources of illumination; and
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.
