The present invention discloses a multi-
station radar station location and joint tracking method based on the distributed PHD (
pulse height discrimination). The method comprises the following steps: S1, receiving echo signals, and performing local tracking filtering
processing; S2, calculating a Chernoff information
divergence formula between posterior in every two radars; S3, constructing an
optimization problem model; S4, solving the optimization model, and obtaining position parameters of all radars relative to other
radar sites; S5, selecting multi-sensor
information fusion criteria; S6, jointing the posterior distribution to change into an
edge density function, and obtaining a fused posterior density function according to the multi-sensor
information fusion criteria; and S7, transmitting the fused posterior density function back to the local
radar in the form of mixed
Gaussian. According to the method provided by the present invention, information of the target can be measured bymultiple radars in the case of the unknown multi-
station radar precise position, multi-station radar location, multi-target tracking and
information fusion can be performed, and the method has a mallcalculation amount, a fast convergence speed, and other characteristics.
