多源数据融合的雷达威力范围评估分析方法研究

Research on the evaluation and analysis method of radar power range based on multi-source data fusion

传统意义上,由于无法找到大量独立同分布的样本,雷达威力范围评估分析是小样本问题。从雷达威力范围方程出发,分析其中和雷达本身工作状态、参数密切相关的个性因素,以及和雷达本身无关的目标环境、气象环境、操作使用等共性因素,对不同因素分别进行处理,形成能够关联不同雷达测试数据的雷达威力范围方程。分析整理历史上目标雷达截面积数据,确定其分布规律;结合雷达测试数据分析共性因素的分布规律;确定雷达威力范围的分布规律,给出雷达威力范围的点估计和区间估计。经过试验分析,所提方法与其他相关方法相比有较好的优越性。

Traditionally,since a large number of independent and identically distributed random variables samples cannot be found,the evaluation and analysis of radar power range is a small sample problem.Starting from the radar power range equation,the individual factors closely related to the working state and parameters of the radar itself,as well as the common factors such as target environment,meteorological environment,operation and use that are not related to the radar itself are analyzed.Different factors are processed separately to form a radar power range equation that can connect different radar test data.Also,the crosssectional area data of historical target radar are analyzed and organized to determine their distribution patterns;the distribution pattern of common factors is analyzed based on radar test data;the distribution law of radar power range is determined,and the point estimation and interval estimation of radar power range are given.The experimental analysis show that this method has better advantages compared to other related methods.
