1. A method for ground surveillance radar performance analysis, the method comprising: receiving by action of a geometric database module a vector of point data items indexed by time offset, the point data items comprising a point probability of detection; determining by action of a scan module a plurality of initial azimuths of a simulated radar signal of a radar tower based on a field-of-regard of the radar tower; calculating by action of a COP lead initial azimuth simulation module a plurality of initial azimuth segment probabilities of detection of a COP lead for each of the initial azimuths respectively based on the vector of point data items and the initial azimuths; and determining by action of a segment COP lead simulation module a segment probability of detection based on the initial azimuth segment probabilities of detection of the COP lead.
