Claim 7:
8. An apparatus of selecting sources of illumination to jam, comprising:
an information obtaining unit configured to obtain the locations of the virtual passive radars and the locations of the sources of illumination and output information thereof; and
a processor configured to:
pick out which sources of illumination to jam from the plurality of sources of illumination, based on the information obtained by the information obtaining unit;
predict sources of illumination used by a virtual passive radar of interest, among the plurality of virtual passive radars, which is disposed within a jamming range with respect to the location of the 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;
select 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
pick 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.
