Research on Simulation Turntable Modeling for Radar Digital Design and Simulation

仿真转台是雷达半实物仿真系统中最常用的试验设备之一,为被测雷达设备提供测试所需的方位、俯仰、横滚等静态和动态空间态势,因此在数字领域实现转台等设备半实物仿真功能,通过对比可以更加全面的对雷达功能和性能进行测试和评估,并能提高雷达设计优化能力。针对半实物仿真中仿真转台的数字化,提出了一种面向雷达数字化设计与仿真的仿真转台建模与仿真方法,基于仿真转台典型的位置、步进、摇摆、转速和动力学等五种运动模式,全面描述了仿真转台运动属性的建模。最后通过具体实验验证了仿真转台数字化模型方法的有效性和可用性。

As one of the most widely used devices in radar hardware-in-the-loop simulation test systems,the simulation turntable provides static and dynamic information,including azimuth,pitch,and roll required for radar test.Realizing the functions of simulation turntables and other interested devices in digital domain can enable more comprehensive test and evaluation of radar functionality and performance as well as radar design optimization.Hence,a simulation turntable modeling and simulation approach is proposed for radar digital design and simulation.The motion attribute modeling of simulation turntables is described in detail,involving five typical motion patterns,namely position,step-movement,swing,roll-speed,and dynamics.Finally,the simulation results prove the feasibility and effectiveness of the proposed approach.
