摘要:

雷达半实物仿真具有成本低、灵活性强、保密性好等诸多优势。但是,随着雷达系统工作模式和处理过程日益复杂、目标姿态日渐多变,雷达半实物仿真在微波暗室脉冲信号等效测量、目标动态特性高逼真模拟等方面的挑战不断涌现。从射频注入式和辐射式两个方面,对雷达半实物仿真技术的发展历程、技术特点和实现难点进行了总结梳理,着重分析了雷达射频辐射式仿真中微波暗室设计、近距离实验、目标特性模拟与测量方法等关键技术。进一步对辐射式半实物仿真中雷达脉冲等效测量面临的瓶颈问题和解决方法进行归纳分析,为雷达半实物仿真的发展方向提供了参考与依据。

Abstract:

Radar hardware-in-the-loop (HWIL) simulation has the advantages of low cost, high flexibility and good confidentiality. However, because the radar mode and processing are complex increasingly and the target altitude is gradually changeable, the radar HWIL simulation is facing various challenges such as the pulse signal equivalent simulation in anechoic chamber and the high-fidelity simulation of target dynamic characteristic. In the aspects of radio frequency injection simulation and radiation simulation, the development of radar HWIL simulation, the technical features and implementation difficulties of radar HWIL simulation are summarized. The key technologies of the radar radiation simulation, such as the anechoic chamber design problem, near-field experiment problem and target characteristics simulation and measurement method are mainly discussed. Furthermore, the bottleneck problems and solutions of pulse radar radiation simulation in anechoic chamber are analyzed, aiming to provide reference and basis for the future research of radar HWIL simulation.

Key words: radar hardware-in-the-loop (HWIL) simulation, injection simulation, radiation simulation, pulse radar, target measurement
