机载前视风切变检测气象雷达的研究进展

机载气象雷达是商业飞机强制安装的机载电子设备，可以称得上是“双眼 ”，它对于保障飞行安全具有举足轻重的作用。目前,机载气象雷达关键技术尚掌握在国外 生 产厂商手中。本文从机载气象雷达系统和机载气象雷达涉及的信号处理技术（包括降水目标 检测、湍流检测和低空风切变检测、地杂波抑制等）两个方面论述了机载气象雷达的发展历 程,指出了其中的关键技术和尚待解决的问题。最后,本文针对下一代具有增强型检测能力的 机载气象雷达系统及其相关技术进行了评述。

Overview on Airborne Forward-Looking Weather Radar with Windshear Detection Capability

Compared to the eyes of the aircraft, airborne weather radar is an imperative avionics equipment for com mercial aviation, which is important and necessary to ensure the flight safety. At present, the key technology of airborne weather radar is mastered by foreign manufactures. This paper gives a comprehensive overview of airborne weather rada r and its related signal processing methods (including precipitation awareness, turbulenc e detection, wind shear detection and ground clutter suppression). The key techn ologies and the problems to be solved are also addressed. Finally, the next gene ration airborne weather radar with enhanced situation awareness and its opening problems are remarked.
