Embodiment Construction

[0037] The present invention mainly adopts the method of computer simulation for verification, and all steps and conclusions are verified correctly on MATLAB-R2013b. The specific implementation steps are as follows:

[0038] Step 1. Initialize relevant parameters. The initialization parameters mainly include: data correlation wave gate size Velocity gate size (v min ,v max )=(10m / s,15m / s), time frame k=1, unassociated measurement matrix

[0039] Step 2. Use the constant false alarm detector to process the radar echo information to obtain the measurement information set Wherein, n is the number of measurements detected;

[0040] Step 3. If k=1, set all measurements z 1 ∈ Z 1 save to matrix , and let k=k+1 and jump to step 2;

[0041] Step 4. If there is no track at the current moment, all measured z k ∈ Z k save to matrix , and skip to step 7;

[0042] Step 5, data association between the measurement of the kth frame and the track:

[0043] 5.1. Predict the s...

Abstract

This paper discloses a track initiation method based on historical measurement information. This algorithm is aimed at the target tracking of Narrow Transmit Multi-Receiver Tracking While Scanning Radar System and Passive Tracking System in actual scenes. Most of the existing tracking algorithms assume that the target can be continuously observed and the measurement information of different targets is synchronized. The characteristics of the present invention: consider the situation that the time interval of the target is observed in the tracking while scanning radar system is uncertain, and make full use of the historical data The tracking information has faster track initiation speed and successful tracking probability; at the same time, the present invention can also solve the problem of track initiation during multi-sensor asynchronous communication in the centralized tracking system and the passive tracking system. Advantages: It makes full use of historical information, is simple to implement, and has a higher probability of successful tracking; it effectively solves the problem of track initiation when measurement information belonging to different targets is asynchronous.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, in particular to the technical field of phased array radar multi-target tracking and the field of passive tracking. Background technique [0002] Phased array radar is an advanced target detection and positioning device that replaces mechanical scanning with electronic scanning. Due to the ability of beam agility, phased array radar has the characteristics of flexible multi-beam pointing and dwell time, controllable space power allocation and time resource allocation, etc. These characteristics determine that phased array radar can realize multi-task and multi-function , and have high measurement accuracy and resolution. [0003] Due to the limited time and energy resources of a radar system, in order to realize the search and tracking of more batches of targets, it is necessary to improve the utilization of time and energy resources of the phased array radar system as much as po...
