The invention belongs to the technical field of communication, and particularly relates to a maneuvering target tracking method in the field of radar signal processing. The method comprises the following steps of: setting a comparison table of an average speed and/or an acceleration filtering value for each filter coefficient according to different types of targets, solving a target average speedand an acceleration filtering value by utilizing a measurement updating module according to a target position measurement value and target state historical data, and then solving a target position anda speed filtering value; then utilizing a delay window delay updating mechanism, adopting a table look-up method to adjust the window length and the filter coefficient so as to adapt to the situationwhether a target is maneuvered or not, once maneuvering is carried out, ensuring the response speed of target tracking, and once the maneuvering transition state is finished, automatically prolongingthe window length to improv
