Apparatus and method of selecting sources of illumination to be jammed for passive radar jamming

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.

A non-transitory computer-readable recording medium storing a computer program, the computer program comprising instructions for a processor to perform a method of selecting sources of illumination to jam when the computer program is executed by the processor, 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.
