Problems solved by technology

However, due to the random sampling characteristics of the SMC method, the estimation of the target state has a certain degree of randomness, which may affect the judgment of the multi-target situation

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 It is a flow chart of a multi-moving target situational awareness method provided by an embodiment of the present invention; the method includes:

[0038] 101: Obtain the measurement set of the target;

[0039] 102: Send the measurement set of the target to at least two parallel sequential Monte Carlo-probability hypothesis density filters for processing, and output a processing result;

[0040] 103: Perform comprehensive analysis on the processing results to obtain the motion status of each target in the target measurement set.

[0041] It should be noted that, the type of the measured variable in the target measured set depends on the type of the situation awareness system sensor.

[0042] It should also be...

Abstract

The invention discloses a multi-moving target situation awareness method, a device and a system. The multi-moving target situation awareness method comprises steps: a target measurement collection is acquired; the target measurement collection is sent to at least two parallel sequential Monte Carlo-probability hypothesis density filters for processing, and a processing result is outputted; and the processing result is comprehensively analyzed, and a moving situation of each target in the target measurement collection is acquired. The parallel sequential Monte Carlo-probability hypothesis density filters are adopted for analyzing and processing multiple moving targets, true paths of the multiple targets are accurately and clearly reflected by multi-moving target situation awareness, and the number of targets at each moment can be accurately estimated.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a multi-moving target situation awareness method, device and system. Background technique [0002] Situational awareness refers to the perception, understanding and prediction of the future state of each element or object in a dynamic environment under a specific time and space. For the multi-moving target scene, in the interference and clutter environment, estimating the time-varying target number and track based on the measurement information including noise is an important task for multi-moving target situation awareness, and also plays a role in the effectiveness of subsequent decision-making. Deep impression. [0003] The traditional multi-target tracking method regards the number estimation and track tracking of multiple moving targets as separate single-target tracking problems, and uses appropriate filters to track each target. The core of this method is the mea...
