Zusammenfassung:The invention discloses a pulse maneuver detection method based on auxiliary state parameters. The method comprises the following concrete steps: 1, building a maneuver kinetic model of a target under a geocentric J2000 inertial system, and adding auxiliary parameters in a state vector; step 2, performing unscented Kalman filtering according to the maneuver kinetic model established in the step 1, and estimating maneuver detection auxiliary parameters; and 3, under the condition that an auxiliary parameter estimation result is obtained in the step 2, judging and detecting a target maneuver according to the characteristics of auxiliary variables. Aiming at the problem that proper auxiliary parameters are difficult to design in a traditional method, through combination with obvious pulse change of the auxiliary parameters before and after pulse maneuver, the probability of target maneuver is calculated on the basis of the change, whether the target has a maneuver or not is finally determined, and the target man
