【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。
[Abstract]:Airborne phased array radar has the capability of fast scanning and agile antenna beam, which can be used to search and track multiple targets. It is widely studied at home and abroad. The real-time simulation of airborne phased array radar system is realized based on Simulink and RTW. Firstly, according to the requirement of airborne phased array radar signal level system modeling and simulation, the modeling and simulation scheme of airborne phased array radar is proposed, and the overall system simulation structure and simulation work flow are designed. The model base of radar system is designed and implemented by using RTW, including transmitter, antenna, signal processing sub-library, environment sub-library, data processing sub-library, resource scheduling and so on. Finally, the airborne phased array radar system is analyzed. The common real-time executable code is generated by using RTW, and the real-time simulation of the system is completed. On the one hand, it verifies that the system can realize the characteristics of searching and tracking multiple targets. On the other hand, the feasibility of using RTW to realize real-time simulation of phased array radar system is also verified.
