本报告描述了对空目标雷达的散射模型,这种模型适用于对空目标交会的雷达引信的计算机模拟。这些模型确定了目标受雷达引信照射时反射到引信的能量特征。目标模型与引信模型相结合,可以确定任何末段交会几何关系情况下引信检测到目标的时刻。典型弹道的引信检测时刻可以同引信的技术性能相比较,以衡量引信的技术性能或者为确定武器系统性能用作整个武器系统模拟的一部分。按照一套基本的技术方法。写出了“鱼床”(Fishbed)、“狐蝙蝠”(Foxbat)和“鞭打者”(Flogger)战斗机、“雌鹿”(Hind—D)直升飞机以及“逆火式”(Backfire)、“眼罩”(Blinder)和B—1轰炸机的目标模型。所有这些模型都是镜面点模型,在这些模型中假定主要的反射是来自目标上少数的闪烁点或镜面点。计算机模拟是在对许多不同引信和目标的速度缩比实验得到的信号特征进行详细研究后得出来的。在模型的研究中,基本的考虑是,保持数学上的简单性,以便使用者对结果产生直观的了解,并且保持运用简便,使模型的应用不受限制。
This report describes the scattering model of an empty target radar, which is suitable for computer simulation of radar fuzes for empty target rendezvous. These models determine the energy characteristics of the target reflected to the fuse when illuminated by the radar fuze. The combination of the target model and the fuze model determines the moment at which the fuze has detected the target in the event of a geometric relationship of any final intersection. The typical ballistic fuze detection moment can be compared to the technical performance of the fuze to measure the technical performance of the fuze or to be used as part of the overall weapon system simulation to determine the performance of the weapon system. Follow a set of basic technical methods. Fishbed, Foxbat and Flogger fighter jets, Hind-D helicopters and Backfire were written, Blinder and the B-1 bomber’s target model. All of these models are specular point models in which the principal reflections are assumed to be from a small number of blinking or specular points on the target. Computer simulations are based on a detailed study of the signal characteristics obtained from velocity-scale experiments of many different fuzes and targets. In model studies, the basic consideration is to maintain the mathematical simplicity so that users have an intuitive understanding of the results and keep it simple to use, leaving the model unrestricted.
