摘要
在多功能雷达脉冲信号出现漏脉冲和虚假脉冲的情况下,错误脉冲导致雷达工作模式识别性能不佳,为此,提出一种雷达字建模的改进方法,并运用数据挖掘中的Apriori关联算法实现对雷达工作模式的准确识别。在雷达辐射源出现漏脉冲和虚假脉冲的情况下,一方面通过增加4个参数来提高识别性能,另一方面通过对错误脉冲参数进行校正,提高雷达字建模的准确率。仿真结果表明,在漏脉冲率和虚假脉冲率为40%时,改进方法的雷达字模型准确率分别提高了8%和6%,对雷达工作模式识别的平均置信度提高了6%。
In the case of missing pulse and false pulse of multi-function radar pulse signal,the performance of radar working mode recognition is not good due to the wrong pulse.Therefore,an improved method of radar word modeling is proposed,and the Apriori correlation algorithm in data mining is used to realize the accurate recognition of radar working mode.In the case of missing pulse and false pulse in radar radiation source,the recognition performance is improved by adding 4 parameters,and the accuracy of radar word modeling is improved by correcting the wrong pulse parameters.Simulation results show that when the miss pulse rate and false pulse rate are 40%,the accuracy of the improved method of radar word model is improved by 8%and 6%,respectively,and the average confidence of radar working mode recognition is improved by 6%.
