21 Claims

1. A computing apparatus comprising:

a processor at an intrusion detection system of a vehicle; and

memory for storing instructions, which when executed by the processor configure the apparatus 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.
