An Improved Robust Filter Algorithm for Manoeuvering Target Tracking With the Unknown and Time‐Varying Noise

ABSTRACT In the natural environment, the unstable radar measurement noise can degrade the tracking performance of the manoeuvering target. In this Letter, the iterative formulation of the noise is simplified, and the noise‐adaptive matrix is introduced to calculate the fading factor of the strong tracking algorithm so that the effect of measurement noise on the fading factor can be corrected in real‐time. The superior performance of the proposed method is verified by comparison with three existi
