摘要
随着多功能相控阵雷达不断发展,其展现的多功能状态和自适应能力强的特性使得传统行为辨识方法无法适应现代战争需求。对此,提出一种基于改进D-S证据理论的雷达行为状态识别方法,该方法将空间运动状态和天线扫描方式作为辅助特征,通过改进D-S证据理论将双链HMM估计结果进行融合,得到最终识别结果。仿真实验结果表明,所提方法能有效解决传统D-S证据理论不能处理的证据冲突问题,且在雷达字提取准确率下降的情况下表现出更强的鲁棒性。
With the continuous development of Multifunctional Phased Array Radar(MPAR),its characteristics of multifunctional states and strong self-adaptive capability make the traditional behavior identification method unable to adapt to the needs of modern warfare.In this regard,a radar behavioral state identification method based on the modified D-S evidence theory is proposed.The method takes the spatial motion state and antenna scanning mode as auxiliary features and fuses the double-chain HMM estimation results through the modified D-S evidence theory to obtain the final identification results.The simulation experiment results show that the proposed method can effectively solve the evidence conflict problem which cannot be handled by the traditional D-S evidence theory,and it shows stronger robustness in the case that the accuracy of radar word extraction decreases.
