Maneuvering Target Tracking with Modified IMM Algorithm Based on Array Radars

Maneuvering target detection and tracking encounter great challenges due to the large measurement error. The characteristics of accurate measurement and different perspectives by array radar and Bistatic radar are used to obtain accurate measurement. To this end, the precise radial-velocity information from bistatic array radar is introduced, and then, we propose a modified interacting multiple model algorithm to improve the tracking accuracy. Simulation results show that the proposed algorithm is superior to traditional tracking algorithms in non-linear scenarios.
