Bearings-only multiple maneuvering target tracking using sensor-array based on MHEKF, PDA/JPDA

"Fake points" come into being in the bearings-only multitarget-tracking system. The method of multihypothesis extended Kalman filter (MHEKF) can only partly eliminate them. To solve it more completely, a new method of sensor array is proposed. First, we used a pre-processing technique to avoid the nonlinearization in the observation function. Secondly, based on the fake points\´ property and geometry, we eliminated them nearly complete using sensor-array. Thirdly, track initialization implemented the idea of the MHEKF and track maintenance using the PDAF or JPDAF algorithm subsectionally. At last, a simulation of two interfering targets tracking in clutter using sensor-array was simulated, the result demonstrates for the effectiveness of this method.
