基于WXR-2100型气象雷达的用户手册,分析了该型雷达在飞机起降阶段探测下击暴流的功能特性,结合某型飞行模拟机的核心仿真环境,研究和实现了一个用于飞行模拟的气象雷达前视风切变探测仿真系统。该系统模拟了气象雷达在飞机起降阶段探测微下击暴流的完整逻辑和功能,可探测下击暴流的实时方位和距离,根据PWS包线生成风切变图像、风切变告警语音和Arinc 429总线数据。同时使用Qt的界面绘图库开发了一个雷达图像桌面显示仿真仪表,该仿真仪表可基于电脑桌面进行风切变图像的测试。该仿真系统最终应用于全动飞行模拟机上,满足前视风切变系统相关的训练要求。

Based on the user manual of WXR-2100 weather radar,the system analyzes the functional characteristic in detecting microburst during the takeoff and landing.Combined with the core simulation environment of a certain type of flight simulator,the system researches and implements a weather radar forward-looking windshear detection simulation system for flight simulation which simulates the complete logic and function of the weather radar to detect wind shear during take-off and landing.The system can detect the azimuth and distance between the aircraft and microburst in real time,generate wind shear image,wind shear warning voice and Arinc 429 bus data according to PWS alerting envelope.Simultaneously,a radar image desktop display simulation instrument was developed by using Qt plot libraries which can test the windshear image based on the computer desktop.The simulation system is ultimately applied to the full flight simulators and meets the training requirement of the forward looking windshear system.
