Embodiment Construction

[0021] In order to reduce the time interval between the discovery of a batch of targets by the radar and the final output of the batch of targets, and improve the accuracy of determining the target track, in the embodiment of the present invention, the air target motion model is first set, and then at least the preset radar Measure the noise parameters, and at least according to the noise parameters measured by the radar, obtain the detection points of the dynamic air targets at different times on the basis of the air target motion model, and then perform a correlation test for each detection point in turn, wherein, for any When a detection point performs a correlation test, if the correlation test objective function of the detection point takes the minimum value, the distance corresponding to the minimum weighted value of the distance between the detection point and each specified track is the distance between the detection point and the target track distance, then it is deter...

Abstract

The invention relates to an identification technique of a target in the sky, and discloses a method and a device for ascertaining an aerial target track. The method for ascertaining the aerial target track comprises setting a motion model of an aerial target, then obtaining sensing points at different moments of a dynamic aerial target based on the motion model of the aerial target, then carrying out a dependence test aiming at each sensing point in sequence, wherein aiming at a arbitrary sensing point, when the dependence test objective function of the sensing point is the minimum value, the corresponding distance of a minimum weighted value in the distances between the sensing point and each appointed track is the distance between the sensing point and the target track, then judging the arbitrary sensing point is a new target point, and at last connecting the judged new target point and the target track to make sure of a track of the aerial target. Therefore, time delay is reduced, and accuracy of a certain target track is improved.

Description

technical field [0001] The invention relates to the identification technology of air target track, in particular to a method and device for determining the air target track. Background technique [0002] In modern high-tech warfare, in order to provide reliable target information for tracking systems, command systems, etc., the detection system is required to determine the trajectory of air targets as accurately as possible. Only by accurately discovering targets, tracking targets and locking targets, Therefore, the exploration and research on determining the track of the air target has far-reaching significance for the technology of determining the track of the air target. [0003] The main function of determining the track is to identify and normalize the radar measurement signals in the case of multiple targets, and then provide an effective decision-making basis for the command and control system, or provide the target track for firepower allocation. It can also provide...
