Embodiment Construction

[0019] (1) Software design and development environment

[0020] The present invention relates to radar tracking spot-track correlation design and development environment as follows:

[0021] Operating system: Windows XP and above, Linux, VxWorks, etc.;

[0022] Software compilation environment: C / C++ compiler.

[0023] (2) Implementation process of track-track association

[0024] The software includes the following seven steps in the implementation process.

[0025] first step:

[0026] according to image 3 Shown are the track sector range and track sector range within the surveillance range of the initial radar station, as well as the perimeter of the radar station. The sectorization range includes the left border and does not include the right border.

[0027] For example, the 360° surveillance range is divided into 16 point track sectors and 16 track sectors (22.5° for each sector), where:

[0028] The range of dot sector 0 is: 0°- 22.5°,

[0029] Range of dot sec...

Abstract

The invention discloses an effective processing scheme of radar system track processing field plot report and track association of a scanning and tracking system. According to the scheme, by designing different sector dividing modes of system tracks and plot reports, the number of the plot reports for performing association detection with the system tracks is reduced, and the goal of reducing wrong association and improving real-time processing is achieved. Meanwhile, the invention further provides a method for association when a radar station is nearby.

Description

technical field [0001] The present invention generally relates to the field of radar data processing of TWS (Track-While-Scan) system, especially in the process of multi-target tracking, when realizing the real-time association selection of radar point track report and maintained system track. The invention provides an effective point track and track correlation processing method, which can improve the real-time performance of conventional correlation algorithms, effectively reduce the occurrence of false correlation, and simultaneously solve the point track and track correlation when the target crosses the radar sky. Background technique [0002] The main function of a modern radar system is to find and track targets. In a TWS radar system, it is usually required to monitor and track a large number of targets (more than 100 batches). In the process of radar information processing, each radar scan cycle signal needs to be Process the judged target point track report, create ...
