Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0030] The target grouping method in the battlefield situation assessment of the present invention is a target grouping method based on hierarchical clustering technology, and the accuracy and speed of its grouping are all unmatched by prior tracking methods. It can effectively support the assessment of the battlefield situation and the decision-making of the battlefield commander.

[0031] refer to figure 1 As shown, target grouping in the battlefield situation assessment of the present invention comprises the following steps:

[0032] First, generate attribute priority list and clustering factor matrix. The attribute priority linked list refers to a linked list in the order of the selected target attributes. Suppose there are two attributes V in the attribute priority linked list i and A i , V i has a higher priority than A i priority...

Abstract

An object clustering method in situation assessment includes the steps: firstly, generating a property priority list and a clustering factor matrix; secondly, segmenting objects in a battlefield into clusters according to the first priority selected from the property priority list and deleting the selected priority from the property priority list; thirdly, judging whether the object quantity in the clusters is greater than the preset threshold value of the object quantity or not, if so, then continuously selecting a priority from the property priority list to segment the clusters, if not or the property priority list is empty, then performing clustering analysis on object data in the bottom clusters to generate mini-clusters according to the object location relationship; and finally, utilizing a fusion algorithm to fuse the mini-clusters, and then acquiring an object group. The object clustering method in the situation assessment overcomes defects in the object clustering and solves the key problem that accuracy and speed of object clustering are low, so that the battlefield situation assessment and policies made by the commander in the battlefield can be effectively supported.

Description

technical field [0001] The invention relates to a battlefield target grouping method, in particular to a target grouping method in situation assessment. Background technique [0002] Due to the diversification of information expressions in the battlefield, the complexity, uncertainty and huge amount of information among the information have resulted; and the battlefield commander cannot process such a huge amount of information in real time, and it is difficult to get rid of the huge amount of "noise". ", which will cause the "Dazzle of War" and "Fog of War" to appear. To address these two issues, situational assessment has been proposed. Among them, target grouping is one of the core technologies in situation assessment. The speed and accuracy of target grouping seriously affect the decision-making of battlefield commanders. Therefore, target grouping has become a hot issue that needs to be solved urgently. Contents of the invention [0003] In order to overcome the def...
