Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.

[0052] The nuclear K-mean track correlation method based on KMDL criterion criterion of the present invention includes the following steps:

[0053] Step 1: Build a typical track correlation scene

[0054] 1. Target measurement generation

[0055] For maneuvering targets, the target motion mode is uncertain, and the motion characteristics are unpredictable. It is difficult to establish a single accurate model for the maneuvering target. Select commonly used typical models from three commonly used target motion models: uniform motion model (CV), uniform acceleration motion model (CA), and uniform turning motion model (CT) to generate target measurement, which is better close to the real motion of the target mode.

[0056] 2. Clutter generation

[0057] In actual applications, in real combat scenarios...

Abstract

The invention discloses a kernel K-means track association method based on KMDL criterion criterion, comprising the following steps: Step 1: constructing a typical track association scene; Step 2: using KMDL criterion criterion to determine the number of target tracks; Step 3: Correlate with the kernel K-means algorithm for the track observation scene. The disclosed kernel K-means track correlation method based on the KMDL criterion criterion of the present invention, based on the target state information, combines the KMDL criterion criterion and the kernel K-means algorithm to solve the complex environment (intensive clutter, close to the target, The multi-target track association problem with unknown number of targets). This method makes full use of the target's motion state information, effectively improving the correlation accuracy rate, the correlation criterion is simple and easy to implement, the calculation amount is small, the correlation accuracy rate is high, and it is not sensitive to target crossing, so it is suitable for navigation in dense and cross-target environments. Trace correlation, suitable for engineering implementation.

Description

Technical field [0001] The invention belongs to the technical field of multi-sensor multi-target tracking, and specifically relates to a nuclear K-mean track correlation method based on a KMDL criterion criterion. Background technique [0002] The multi-sensor multi-target tracking system mainly receives the local track information from each sensor system through the data link, and then calculates the core issues such as correlation, registration, and fusion of the local track information to form a coordinated detection and fusion target track. [0003] Multi-sensor cooperative target tracking can achieve precise tracking of targets. In practical applications, there are multiple targets to be tracked. At this time, it is necessary to correctly determine the correspondence between the measurement information received by the sensors and the target of interest. However, due to the clutter generated by the false radiation source, interference clutter and false targets, the uncertainty...
