【摘要】 机载相控阵雷达具有天线波束快速扫描和捷变的能力，可实现对多目标的搜索和跟踪，在国内外得到广泛研究。本文基于Simulink和实时工作箱（RTW）实现了对机载相控阵雷达系统的实时仿真。首先，根据机载相控阵雷达信号级系统建模仿真需求，提出了机载相控阵雷达建模仿真方案，设计了系统仿真总体构成和仿真工作流程。其次，利用RTW设计实现了雷达系统模型库，包括发射机、天线、信号处理子库、环境子库、数据处理子库、资源调度等。最后，对搭建的机载相控阵雷达系统进行分析，并利用RTW将系统生成普通的实时可执行代码，完成系统实时仿真。一方面验证了系统可实现对多个目标搜索和跟踪的特性，另一方面也验证了利用RTW实现相控阵雷达系统实时仿真的可行性。更多还原

【Abstract】 With the rapidly scanning and agility of antenna beam, airborne array radars areable to search and track multi-target, which is widely investigated at home and abroad.In this dissertation, the real-time simulation of the airborne array radar system isachieved based on the Simulink and real-time workshop (RTW).Firstly, according to the demands of the modeling and simulation of airbornearray radar system at the signal level, a design scheme of airborne array radar systemsimulation is put forward, and the system overall structure and the simulation processis designed. Secondly, the model library of the radar system is established, includingtransmitters, antennae, signal processing subsystems, environment subsystems, dataprocessing subsystems, resource scheduling, etc. Finally, the analysis of theconstructed airborne array radar system is presented. Then, the real-time executedcodes are generated based on the RTW and the real-time simulation is accomplished.On the one hand, it is demonstrated that the constructed system can accomplishsearching and tracking multi-target. On the other hand, the feasibility of realizing thereal-time simulation of the airborne array radar system based on the RTW is alsoverified.更多还原
