本文介绍度量技术在一个电子支援措施(ESM)数据处理方案中的运用情况,该方案应英国国防部(采购机关)的需求而研制的,研制单位是“系统工程师咨询联合会史密斯有限公司”(Sm-ith Associates Consulting System EngineersLimited).该 ESM 数据处理方案的辅入是描述照射—部 ESM接收机的雷达特征的数字脉冲数据,它的输出则是一个连续更新的辐射源表,表中列出了环境中出现的辐射源,并规定了这些辐射源的被推测参数.在这个方案的下列两个不同处理阶段中,度量技术起重要作用.首先用在到达方向(DOA)—射频(RF)脉冲过滤(筛选)处理中,其次用在辐射源表更新处理中.在 DOA—RF 过滤阶段中,利用脉冲的两维(参数)群集分析方法来处理脉冲.这种方法既可确保来自单个辐射源的脉冲不被分裂成几批不同的脉冲群,又能确保对来自不同辐射源的脉冲被分离开,除非它们的参数在 DOA 和 RF 这两个参数上都发生重叠.一般来说,采用一维过滤方法不能获得相同的结果。方案中使用了—种高效计算的方法,度量技术在此方法中用于一组组脉冲群,脉冲的分组是通过先是 DOA 然后是 RF 参数的一维过滤方法取得的.在辐射源表更新处理过程中,采用度量技术可确保已在辐射源表上记载过某个辐射源来的脉冲能正确地与辐射源表的条目关联起来。而不会被当作初次发现的一个新辐射源添加到表格中去.这就克服了下述问题,即,对某些辐射源来说,当它们改变工作方式时,其某些参数可能会不连续地改变.倘若某些参数仍能维持近乎恒定的话,那么,采用度量技术就能确保进行正确的关联功能.
This article describes the use of metrology technology in an Electronic Support Measures (ESM) data processing solution developed at the request of the Department of Defense (Procurement Agency) of the United Kingdom and developed by Systems Consultant Consultants Smith Inc. Sm-ith Associates Consulting System Engineers Limited.) The ESM data processing scheme is supplemented with digital pulse data that describes the radar characteristics of the Shooting-Part ESM receiver and its output is a continuously updated table of radiation sources listed in the table The radiation sources that appear in the environment and specify the speculative parameters for these radiation sources. Metrology techniques play an important role in the following two different processing stages of this approach: First, measurement is performed in DOA - RF, Pulse filtering (filtering), and secondly in radiation source table update processing. In the DOA-RF filtering phase, pulsed two-dimensional (parametric) cluster analysis methods are used to process the pulses. This approach ensures that light from a single radiation The source pulse is not split into batches of different pulse groups, but ensures that pulses from different radiation sources are separated unless their parameters are at DOA and R F overlap in both parameters.In general, using the one-dimensional filtering method can not get the same result. In the scheme, a method of efficient computation is used in which the measurement technique is applied to a group of group impulses obtained by a one-dimensional filtering method that first DOA and then RF parameters.When the radiation source table updating process In the process, metric techniques ensure that pulses from a source already recorded on the source table can be correctly correlated with the entry on the source table. Rather than being added to the table as a new source of radiation that was first discovered.This overcomes the problem that for some radiation sources certain parameters may change as they change their mode of operation Discontinuously changing.If some of the parameters can be maintained almost constant, the use of measurement techniques to ensure the correct correlation function.
