This application relates to a passive coherent location (PCL) system. In one aspect, the PCL system includes a signal measurement device configured to receive a plurality of signals from a plurality of illuminators and generate an In-phase signal and a Quadrature signal corresponding to each illuminator using the received signals. The PCL system also includes a signal processing device configured to detect a first target using the In-phase and Quadrature signals and measure a bistatic range of the first target and a bistatic velocity of the first target to generate a plurality of pieces of line track information corresponding to the first target. The PCL system further includes a locating device configured to generate target track information of the first target using the line track information and predict a position vector and a velocity vector of the first target using the target track information.
