Research on α-β adaptive dual-channel filtering algorithm based on low-speed target

α-β filtering method is often applied to low-speed target tracking filtering, but it is not suitable for the strong maneuvering target tracking. Therefore, an adaptive dual-channel α-β filtering algorithm is proposed to solve the problem above. The algorithm can choose the right channel to improve the filtering effect according to the values´ difference between observations and forecasts. This paper introduces the principle of dual-channel filter and verifies its positive effectiveness by contrast experiments.
