摘要
Abstract
An attention-guided multi-dimensional feature fusion identification method based on a distributed radar system is pro-posed in this paper.In this method,a multi-feature fusion network is designed to focuse on different echo characteristics,and multi-modal information is projected into a high-dimensional space for effective separation.The network comprehensively utilizes the energy consistency of target echoes,velocity projection consistency,spatial positioning correlation,and spectral distortion fea-tures formed by genuine reflections,paying attention to features of signals at different scales by means of multi-scale convolution;moreover,it enhances the representational capacity of network by establishing an attention mechanism among different scales and features.The identification performance is validated and compared by constructing a dataset based on electromagnetic simulations,and designing various signal to noise ratio and baseline length conditions.Experimental results demonstrate that under challenging conditions of a signal to noise ratio of-6 dB and a short baseline of 2 km,the proposed method achieves a recognition rate of 97.4%,showing significant improvement over traditional methods.Component-wise and feature-wise ablation studies confirm the effectiveness of key designs,including the attention mechanism,multi-scale convolution,and multi-feature fusion.As the proposed method is grounded in physical characteristics without relying on specific signal modes,it offers a more robust solution for true-false target identification in complex electromagnetic environments,thereby enhancing radar capability against deception jamming.关键词
