Anti-ship missile trajectory tracking based on CS_UKF and interacting multiple models

Anti-ship missile is a kind of typical high maneuvering target, which has the characteristics of strong motor and multiple mobile. Especially its unique form of “snake maneuver” brought great difficulties to the tracking system. This article used the IMM algorithm and the “current” statistical model constituted model set, together with the method of UKF filter which avoid extended kalman tedious Jacobi matrix calculation, then we get a new method for anti-ship missiles tracking. Results show that the method has good tracking performance to strong maneuvering target just like anti-ship missile.
