Method and apparatus for generating deception target information for deception jamming of passive radar

An apparatus for generating deception target information, comprising:

• a data acquisition unit configured to acquire various data for generating deception target information;
• and
• a processor configured to generate deception target information based on the various data acquired by the data acquisition unit,
• the processor further configured to:
• set a plurality of third transmission sources pre-selected based on a movement path of a jammer among the various data as jamming channels;
• set, for each of the set jamming channels, a passive radar reference position to be used as a reference for deception jamming of a passive radar according to presence or reliability of prior information on a position of the passive radar among the various data;
• group the set jamming channels into a single group or a plurality of groups according to the operating environment and operating purpose among the various data;
• analyze the deception target settable area based on positions of the third transmission sources, the passive radar reference position, and a movement path of the actual target for each group;
• set a deception target movement path in a movement time of the actual target in the deception target settable area analyzed for each passive radar reference position and each jamming channel group;
• and
• derive deception target information during the movement time of the actual target based on the passive radar reference position, the positions of the third transmission sources of the corresponding group, the movement path of the actual target, and a movement path of a virtual deception target for each deception target movement path.

A non-transitory computer-readable recording medium storing instructions, when executed by a processor, causing the processor to perform a method, the method comprising:

• setting a plurality of third transmission sources pre-selected as jamming channels based on a movement path of a jammer as jamming channels;
• setting a passive radar reference position to be used as a reference for deception jamming of a passive radar according to presence or reliability of prior information on a position of the passive radar for each of the set jamming channels;
• grouping the set jamming channels into a single group or a plurality of groups according to an operating environment and an operating purpose;
• analyzing a deception target settable area based on positions of the third transmission sources, the passive radar reference position, and a movement path of the actual target for each group;
• setting a deception target movement path in a movement time of the actual target in the deception target settable area analyzed for each passive radar reference position and each jamming channel group;
• and
• deriving deception target information during the movement time of the actual target based on the passive radar reference position, the positions of the third transmission sources of the corresponding group, the movement path of the actual target, and a movement path of a virtual deception target for each deception target movement path.
