摘要
改进了复杂电磁环境下雷达辐射源模糊识别算法。改进算法通过证据组合对模糊隶属度进行融合,很好地解决了识别中的不确定性,错误的识别结果经过融合后得到去除。采用最优隶属准则进行雷达辐射源类别决策,融合后的辐射源正确识别率得到明显提高。仿真结果及对比实验表明,相比于模糊识别算法,信噪比不小于0dB时,改进算法的正确识别率大于90%。
Radar emitter identification algorithm based on fuzzy theory is improved. By analyzing fuzzy subordinate values and then using evidence combination principle to combine these values, the recognition uncertainty is solved. The class decision-making is carried out based on optimization subordinate rule, the accurate recognition rate is increased. Simulation experiment shows that new algorithm identification rate more than 90% when SNR higher than 0 dB compared with fuzzy identification method.
