Problems solved by technology

However, due to factors such as technological development and enemy secrecy, new types of targets may appear in war at any time, and it is easy to identify new types of targets as known target types, resulting in wrong decision-making on the battlefield

Abstract

The invention discloses an unknown target identification method based on attribute weight fusion. The method comprises the following steps: 1, generating a Gaussian distribution training model according to a target sample data set; 2, expanding a test sample t detected by the sensor into a Gaussian test model; 3, calculating the matching degree of the Gaussian test model and the Gaussian distribution training model, and generating evidences on all attributes; 4, performing weighted fusion on evidences on each attribute; and 5, determining the target type of the test sample according to the fusion result in the step 4. According to the method, on the basis of a Gaussian distribution model, in combination with the advantages of processing uncertain information and incompleteness of an identification framework of a generalized evidence theory, an area segmentation method is adopted to assign weights to attributes during attribute evidence fusion; besides, the improved generalized evidencecombination rule can process uncertain information more flexibly and effectively, errors are smaller, and the accuracy of target recognition and recognition of targets of unknown types are improved.

Description

technical field [0001] The invention belongs to the field of target recognition, in particular to an unknown target recognition method based on attribute weight fusion. Background technique [0002] Battlefield situation assessment is greatly related to the victory of the war and is crucial to battlefield decision-making. Target recognition is the premise and key of situation assessment. However, the objects of battlefield target recognition are often the targets that intrude into and invade our territory, territorial waters, and volleys by mistake, including non-cooperative targets and hostile targets. In order to identify battlefield targets, researchers need to establish a type template library for all possible target types, so as to match the detected targets with the targets in the template library to identify detection targets. However, due to factors such as technological development and enemy secrecy, new types of targets may appear in war at any time, and it is eas...
