Two targets example. (a) 3-dB SNR range profile for two targets and with two clutter peaks (arrows) at 15.33 and 22 m, and few higher order multipath shown by (red triangle symbol), (b) elliptical and circular loci after clustering and wall association. In (b), direct path circles (solid black) centered at radar (blue asterisk symbol), bistatic ellipses (blue) and monostatic circles centered at virtual radars (red asterisk symbol), w.r.t wall-1 (solid), wall-2 (dashed), and wall-3 (dotted), and the intersections of the loci (blue square symbol) for the two estimated target locations.
