Abstract

The invention belongs to the radar technical field and relates to a marine navigation radar data interconnection-based multi-target tracking method and system. The method includes the following steps that: a plurality of groups of radar data are collected from a radar; appropriate wave gate parameters are selected according to a tracking duration and a tracking state; the overlap ratio, distance ratio, shape ratio and energy ratio of navigation trajectory data and a plurality of point trajectory data are calculated through a point trajectory data and navigation trajectory data processing unit, so that an interconnection condition can be obtained; and a target point trajectory data tracking result is obtained through a target point trajectory output point. According to the marine navigation radar data interconnection-based multi-target tracking method and system of the invention, besides position information, the features of targets, such as the shape ratio and energy ratio are utilized; and multidimensional information judgment is utilized, and therefore, when multi-target tracking is performed in a dense clutter environment, the tracking accuracy of the targets can be ensured, and the probability of false matching can be decreased.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a multi-target tracking method and system for data interconnection of marine navigation radar. Background technique [0002] In recent years, with the complex and changeable application environment, radars are required to have multi-tracking target tracking capabilities, and can simultaneously realize multi-tracking target tracking; the basic concept of multi-tracking target tracking was published by Wax in 1955 in Applied Physics Journal In 1964, Steer published a paper entitled "The Optimal Data Association Problem in Surveillance Theory" on IEEE, which became the forerunner of multi-tracking target tracking, but Kalman filtering was not yet widely used at that time. , Steer used a track bifurcation method to solve the data association problem; in the early 1970s, in the presence of false alarms, the Kalman filter method (Kalman) was used to systematically track and track multipl...
