Abstract

The invention belongs to the technical field of radar moving target tracking and particularly relates to a before-radar-target-detecting tracking method based on track enhancing. According to the tracking process, first, for multi-frame original data, non-parametric track initial batch processing operation is carried out, and a target trace point set is obtained; then according to target track state parameters updated in real time and errors in measurement, a corresponding parameterization track enhancing operator is designed; and finally current measuration is combined, and a parameterization track enhancing method is used for carrying out prediction tracking. The method is characterized in that closed loop feedback is achieved, during track enhancing operation, multi-frame measuration and states can be fully used, detecting tracking accuracy and precision can be improved, the method has the advantage that under the condition of the low signal-to-noise ratio, detecting and tracking integration processing can be achieved, and the method can be used in the field where monitoring systems such as radar are used for detecting and tracking a long-distance highly-maneuvering target with weak echo signals.

Description

technical field

[0001] The invention belongs to the technical field of radar moving target tracking, and particularly relates to a radar target tracking method based on trajectory enhancement. The integrated processing of the detection and tracking of long-distance maneuvering targets with weak echo signals by the surveillance system. Background technique

[0002] In modern warfare under the high-tech background, continuous monitoring of the battlefield can provide rich strategic and tactical information for applications such as situation assessment and command, and plays a key role in winning the war. With its all-day and all-weather working characteristics, radar has always been the core of the battlefield surveillance system.

[0003] Aiming at the problem of detection and tracking under the condition of low signal-to-noise ratio, in order to avoid the missed detection of the target caused by the low signal-to-noise ratio, the Track Before Detect (TBD: Track Before Detec...
