Target threat assessment method based on improved grey target theory and medium

Abstract

The invention discloses a target threat assessment method based on an improved grey target theory and a medium. The method comprises the steps of 1, obtaining a decision matrix and a threat attributeweight vector of a to-be-assessed target; 2, constructing a virtual target decision matrix; 3, constructing a combined decision matrix; 4, calculating a standardized combination decision matrix; 5, calculating a target center absolute difference matrix; 6, calculating a target center coefficient matrix; 7, calculating an integrity vector and a target center degree vector; 8, extracting a target center degree vector of the virtual target; 9, performing threat sorting of the targets according to the sizes of the target center degree vectors of the targets; and 10, performing threat grading on the target. Based on the improved grey target theory and the threat attribute integrity, threat sorting and threat level calculation of battlefield targets are achieved, and the defects that a traditional threat evaluation algorithm does not calculate the threat level, and a single target and a threat attribute default target cannot be evaluated are overcome.

Description

technical field [0001] The invention belongs to the technical field of information fusion and can be used for target threat assessment, in particular to a target threat assessment method and medium based on improved gray target theory. Background technique [0002] Yuan Jinxu of the Air Force Command Academy and others proposed an algorithm of "air target threat assessment and ranking based on gray target theory". Mathematical model of threat ranking to calculate target threat ranking. This method conveniently converts the threat assessment process from qualitative to quantitative, and can quickly generate target threat rankings. Assuming m enemy targets and n feature elements, the specific steps of gray target theory threat ranking are as follows: [0003] (1) The original sample matrix D=(d ij ) m×n , carry out normalization processing, and obtain the normalization matrix H=(h ij ) m×n : [0004] [0005] [0006] (2) Set the target factor standard mode (ie bu...
