Range doppler consistency check for radar ghost target detection

A method, comprising:

• receiving, at an intrusion detection system (IDS) of a vehicle, an indication of a range and a velocity of a plurality of targets based on radar signals;
• tagging a first one of the plurality of targets as a potential ghost target based on the velocity of the plurality of targets;
• issuing a command to cause a perturbation of a speed of the vehicle to induce a change in distance between the vehicle and the first one of the plurality of targets as the potential ghost target;
• receiving an indication of an updated range of the first one of the plurality of targets;
• and
• confirming the potential ghost target as an actual ghost target based on the range of the first one of the plurality of targets and the updated range of the first one of the plurality of targets.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by processing circuitry of an intrusion detection system (IDS) of a vehicle, cause the IDS to:

• receive an indication of a range and a velocity of a plurality of targets based on radar signals;
• tag a first one of the plurality of targets as a potential ghost target based on the velocity of the plurality of targets;
• issue a command to cause a perturbation of a speed of the vehicle to induce a change in distance between the vehicle and the first one of the plurality of targets as the potential ghost target;
• receive an indication of an updated range of the first one of the plurality of targets;
• and
• confirm the potential ghost target as an actual ghost target based on the range of the first one of the plurality of targets and the updated range of the first one of the plurality of targets.
