Aerial target threat assessment method based on dynamic TOPSIS

Abstract

The invention discloses an aerial target threat assessment method based on dynamic TOPSIS, relates to an aerial target threat assessment method, and belongs to the field of threat assessment in data fusion processing. The method comprises the steps: firstly obtaining the sequential value of threat attributes of the aerial target at a discrete time node according to the original data of the aerial target, and predicting the change trend of the sequential value of threat attributes of each target with time through employing a GM(1, 1) model with boundary value correction; carrying out the weight calculation of an obtained dynamic threat attribute value prediction sequence through an entropy weight method, and further constructing a weighted standardized decision matrix; carrying out the assessment of the aerial threats at future time nodes through employing a TOPSIS method, and obtaining the dynamic prediction assessment result of the threat degree of the aerial target. The method can achieve the dynamic prediction assessment of the threat degree of the aerial target in variable environments of battlefields. The method can be used in the field of air defense command, remarkably shorten the reaction time of the air defense command, and meet the requirements for the instantaneity of air defense.

Description

technical field [0001] The invention relates to an air target threat assessment method, in particular to a dynamic TOPSIS-based air target threat assessment method, which belongs to the threat estimation field in data fusion processing. Background technique [0002] In modern warfare, the air striker adopts high, medium, and low-altitude multi-level, multi-batch, and multi-directional simultaneous saturation attack tactics, which makes air defense operations face severe challenges. In the process of air defense operations, the command system must analyze and evaluate the threat of incoming targets based on battlefield intelligence, so as to quickly and accurately implement air defense firepower allocation and tactical decision-making. In the modern information battlefield, the defender can obtain the raw data of air threat targets from various advanced reconnaissance equipment and battlefield sensors, and obtain target threat attribute information through data preprocessing ...
