摘要
根据现有的雷达抗干扰性能评估方法存在的问题,提出了一种基于高维量测特征空间几何分析的雷达抗干扰性能评估方法。该方法将抗干扰试验中雷达得到的量测数据映射到高维量测特征空间中,利用量测数据的多元密度分布的几何特征定义量测误差影响因子(MEIF)、量测稳定性影响因子(MSIF)和干扰影响因子(JIF),定量分析干扰对雷达的影响以及雷达的综合抗干扰性能。计算机仿真表明,新的评估指标可以准确反映雷达的抗干扰性能,实验结果与理论分析相符。
According to the problems in radar ECCM performance evaluation, a statistic method based on geometry analysis in high-dimensional measurement feature space is proposed. The method projects the measurement information into the high-dimensional measurement space and utilizes geometry feature of the multivariate density distribution to define the measurement error impact factor (MEIF), the measurement stability impact factor (MSIF) and the jamming impact factor (JIF) to evaluate the ECM effect as well as the comprehensive ECCM performance. It is proved by computer simulation that the method is able to describe the radar ECCM performance exactly and the results are consistent with theoretic analysis.
