Intelligent decision support system design and implementation method for unmanned aerial vehicle SAR image automatic target recognition

Abstract

The invention discloses an intelligent decision support system design and implementation method for unmanned aerial vehicle SAR image automatic target recognition. The method comprises constructing a feature library and an inference engine. The specific process of constructing the feature library is as follows: 11) performing segmentation detection on a target in the SAR image; 12) carrying out target false alarm elimination and target calibration on the SAR image; 13) constructing a multi-scale space based on a Gaussian difference model; and 14) taking multi-resolution features of the SAR image, and constructing a feature library according to the extracted multi-resolution features. The specific process of constructing the inference engine is as follows: 21) constructing a training set and a test set by using the extracted multi-resolution features of the SAR image; 22) constructing a multi-scale multi-core support vector classifier; and 23) training and testing the multi-scale multi-core support vector classifier, and performing automatic target identification of the SAR image by using the trained and tested multi-scale multi-core support vector classifier to construct an inference engine. The method can realize automatic target identification of the SAR image.

Description

technical field [0001] The invention relates to a design method of an intelligent decision support system, in particular to a design and implementation method of an intelligent decision support system for automatic target recognition of UAV-borne SAR images. Background technique [0002] Decision Support System (DSS) uses information technology as a means to apply theories and methods of management science, computer science and other disciplines, aiming at semi-structured or unstructured decision-making problems, by providing background materials and assisting in clarifying problems It is a human-computer interaction information system that helps managers make correct decisions by modifying and perfecting models, enumerating possible solutions, and conducting analysis and comparison. [0003] In the 1970s, the development of operational research models was relatively complete, multi-objective decision-making analysis broke through the framework of a single utility theory, co...

Problems solved by technology

However, this type of unmanned combat system relies more on human-in-the-loop control, and has not achieved true automatic target recognition, nor has it been designed and effectively used from the perspective of intelligent decision support.
