摘要
在多传感器协同侦察场景下,电子情报侦察系统能够对同一目标的雷达辐射源信号参数进行长时间连续地收集,经过长年累月的数据积累,能够形成对目标较为完整的雷达信号数据积累。文中针对协同侦察场景采集的海量数据搭建了一套多维数据存储及分析系统以积累数据,并且在考虑时间和空间容差的前提下将电子侦察数据与有源航迹关联,进而推导出目标位置与雷达信号之间的关联关系。最后,以某目标两次航行活动的实侦数据为例,从辐射源信号参数、时域、空域三个维度进行雷达信号分布规律分析,分析结果表明同一目标的辐射源参数与其航行活动过程进度和空间地理位置存在一定的关联关系。
In the multi-sensor cooperative reconnaissance scenario,the electric intelligence reconnaissance system can collect the radar emitter signal parameters of target in different mission areas for a long time.Combined with the target position information intercepted by active reconnaissance means,a relatively complete radar signal data accumulation can be formed after years.A set of multidimensional data storage and analysis system is built to accumulate data.On the premises of considering the tedious time and space,the electric reconnaissance data is associated with the active track.Furthermore,the correlation between the target position and the radar signal is deduced.Finally,taking the actual investigation data of a target as an example,the radar signal distribution law is analyzed from three dimensions of signal parameters,time domain and airspace.The results show that there is a certain correlation between the parameters of radiation source of same target and its navigation time and spatial location.
