为了提高威胁雷达情况分析人员对付较高的辐射器密度和伴随威胁雷达所增加的信号复杂性的能力,需要将新的接收机和后信息处理器(Post-Processor)分系统技术综合起来。先进的计算机模拟技术正在发展着,它允许雷达分析人员能精确地建立复杂雷达系统的设计模型,同时可评估它们的复杂性和弱点。根据通用雷达系统和它们的有关的分系统的程序库进行的动态模拟,能用来预测基于输入波形信号,以及每一分系统单元设计参数的技术要求的雷达硬件系统的性能。情报分析人员或雷达设计师用动态模拟能力,能评价不同的接收机技术,来选择设计方案并提出特定部件的非线性,精确模拟不良工作环境中的系统性能,可以支持并明确对系统在实际环境中的异常情况的理解。可用表示每一分立单元的特性的数学模型或固有的传递函数图解表示动态模拟软件。利用终端情报分析人员以人机对话形式,通过执行程序的连接或者通过使用预置程序的缺席结构,以方框图形式建立一个系统模型。模拟必须是组件化的和结构化的,以便能利用系统/分系统的选择性组合实现逼真和确定的工程算法。动态模拟计算机软件从情报机构的数据库、电子战以及武器设计结构的数据库获得有关雷达威胁信号特征的输入。此种取得信息的方式是以使用公共的模拟输入/输出格式、数据库结构和通用的数据字典环境为基础的。由于使用模拟数据库共享的共性,从而有利于武器系统设计者和情报机构的威胁系统分析人员,以及电子战机构的成员。
To improve the ability of threat radar analysts to cope with higher radiator densities and signal complexity associated with threat radars, new receiver and Post-Processor subsystem techniques need to be combined. Advanced computer simulation technologies are under development that allow radar analysts to precisely model the design of complex radar systems while assessing their complexity and weakness. Dynamic simulations based on general radar systems and their associated subsystems libraries can be used to predict the performance of a radar hardware system based on input waveform signals and the technical requirements for each subsystem unit design parameter. Intelligence analysts or radar designers use dynamic simulation capabilities to evaluate different receiver technologies to choose a design solution and to propose the non-linearity of specific components to accurately model system performance in poor working conditions, to support and clearly define the system’s performance in practice An understanding of the anomalies in the environment. The dynamic simulation software may be diagrammatically represented by a mathematical model representing the properties of each discrete unit or by an intrinsic transfer function. A system model is created in the form of a block diagram by using human-machine dialogues by terminal intelligence analysts, by executing program connections, or by using the absence structure of a preprogrammed program. Simulation must be modular and structured so that realistic and deterministic engineering algorithms can be implemented using selective combinations of systems / subsystems. Dynamic Simulation Computer Software Obtains input regarding the characteristics of radar threat signals from databases of intelligence agencies, electronic warfare, and weapons design structures. This way of getting information is based on using a common analog input / output format, a database structure, and a common data dictionary environment. Because of the commonalities of using simulated database shares, threat system analysts at arms system designers and intelligence agencies, as well as members of the electronic warfare agencies, are favored.
