【摘要】 现代雷达的功能日益多样化和复杂化，这促使雷达系统的建模与仿真技术也必须不断发展。利用计算机技术进行雷达系统的建模和仿真早已被广泛采用，而现代EDA技术及其仿真工具更是将雷达系统仿真带入了全新的阶段。本文基于最新EDA仿真平台System View进行了雷达系统的建模和仿真。主要内容包括：介绍System View仿真平台的使用及基于此平台上的建模与仿真方法；进行相关雷达杂波的建模与仿真并构建了相关雷达杂波模块库，其中采用了零记忆非线性变换法(Zero Memory Nonlinearity,ZMNL)与球不变随机过程法(Spherically lnvariantRandom Processes,SIRP)，给出了每种杂波的产生模型及仿真结果；结合单脉冲测角法与脉冲多普勒雷达信号处理系统构建了单脉冲雷达系统模型，进行了仿真并给出了部分仿真结果。本文的工作为雷达杂波与雷达系统的建模、仿真与建库打下了基础，积累了经验。更多还原

【Abstract】 Increasingly diversification and complication of the function of modern radar urge the never-ending progress of the modeling and simulation of radar system. The application of computer technology on modeling and simulation of radar system has been abroad adopted for a long time, and modern EDA technique and simulation tools make the simulation of radar to a bran-new phase. In this paper, the modeling and simulation of radar system based on the new EDA simulation platform-System View are set up, the primary contents are as follows: the use of the simulation platform-SystemView and the method of modeling and simulation based on System View are introduced; the modeling and simulation of the correlated radar clutter are progressed and module database of correlated radar clutter is constructed, Zero Memory Nonlinearity(ZMNL) and Spherically Invariant Random Processes(SIRP) are adopted , the producing models and simulation results of every kind of clutter are given; combining with the method of monopulse angle-measure and the signal processing system of the pulse doppler radar, monopulse radar system model is constructed, the simulation is progressed and some simulation results are given. The work of this paper can be served as the basis of future research on the modeling, simulation and module databases construction for radar clutter and radar system, and accumulated considerable experience.更多还原
