Method and System for Indoor Multipath Ghosts Recognition

A system for indoor multipath ghost recognition comprises:

• a radar with collocated antennas;
• and
• a processor operably coupled to the radar,
• wherein the processor is configured to generate a two-dimensional Range-Doppler map for radar data frames,
• wherein the processor is further configured to apply a temporal clustering algorithm to the radar data frames,
• wherein the processor is further configured to apply a linear pattern extraction algorithm on the two-dimensional Range-Doppler map, and
• wherein the two-dimensional Range-Doppler map comprises detections from a target, a first-order ghost, and a second-order ghost, and wherein the first-order ghost and the second-order ghost correspond to indirect propagation paths between the radar and the target that include one or more reflections from a static object.
