The invention belongs to the technical field of multi-
radar networking plot fusion, and particularly relates to a multi-
radar plot fusion method. The method comprises the following steps of 1, receiving multiple pieces of
radar measurement data, conducting space alignment and setting a uniform measurement coordinate
system; 2, judging whether the
radar measurement data all contains target
Doppler velocity information or not, if yes, executing the step 3, and otherwise, executing the step 6; 3, conducting
time alignment; 4, conducting plot association and plot fusion to obtain fused plot information; 5, conducting track association with a formed track and filtering updating by utilizing the fused plot information, and executing the step 7; 6, sorting the data by time, and conducting track association with the formed track and filtering updating in sequence by utilizing the sorted data; 7, conducting
track initiation by utilizing the radar data which does not participate in track association; 8, outputting a track result. The multi-radar plot fusion method is beneficial to prolonging the target detection distance and improving the tracking precision and the maneuvering target tracking performance.
