飞机尾流是空气动力飞行器飞行时产生的特有流体力学特征,具有强烈、稳定、持续时间长、空间尺度大等特点,因此可被雷达、激光雷达、声纳等传感器有效探测。飞机尾流的湍流特性使其具有独特的电磁散射特性,尾流的雷达探测技术具有重要的军用和民用价值。本文从尾流的电磁计算与模拟、尾流的测量实验、尾流探测的理论体系3个方面,梳理了尾流探测技术的国内外研究现状,指出该项技术在民航飞行、反隐身探测、雷达抗干扰、航母起降、目标跟踪5个方面具有的应用潜力。尾流探测雷达的研制和原理性验证试验的开展,可进一步推动中国在机场航空、雷达反隐身等领域的发展。
Aircraft wake is the unique hydrodynamic characteristic of aerodynamic aircraft during flight. It has characteristics of strong, stable, long duration and large space scale. It can be effectively detected by radar, lidar, sonar and other sensors. The turbulent characteristics of aircraft wake make it have unique electromagnetic scattering characteristics, wake wake radar detection technology has important military and civilian value. This paper reviews the current research status of wake detection technology at home and abroad from three aspects of electromagnetic calculation and simulation of wake flow, measurement experiment of wake flow and the theoretical system of wake detection. It is pointed out that this technology has great potential in civil aviation flight, anti-stealth detection, Radar anti-jamming, carrier take-off and landing, target tracking 5 has potential applications. The development of the wake detection radar and the development of the principle verification test can further promote the development of China in the field of airport aviation and radar anti-stealth.
