隐身技术由于能够有效地提高作战飞机的突防能力和生存能力,因而其发展得到当今世界各国军方的极大重视。许多国家将其列为本国未来国防科技发展的关键技术,在发展下一代作战飞机等航空武器装备时,将隐身作为一项基本的技术指标要求。一、隐身技术的含义隐身是个通用的术语,是控制目标的可观测性或控制目标特征信号的技巧和技术的结合。与隐身有关的术语还包括特征信号控制、降低雷达截面、特征信号互动、低可观测性、十分低可观测性等。目标特征信号是描述某种武器系统易被探测的一组特征,包括电磁(主要是雷达)、红外、可见光、声、烟雾和尾迹6种特征信号。据统计,空战中飞机损失80～90%的原因是由于飞机被观测。降低平台特征信号,就降低了 Stealth technology, as it can effectively improve the penetration and survivability of combat aircraft, has drawn great attention from the military in various countries of the world today. Many countries have listed it as the key technology for the development of national defense science and technology in their own country. Stealth as a basic technical indicator is required in the development of aviation weaponry and equipment such as the next generation of combat aircraft. First, the meaning of stealth technology Incognito is a common term, is to control the target’s observability or control of the characteristics of the target signal combination of skills and techniques. Incognito terms also include signature control, radar cross-section reduction, feature signal interaction, low observability, and very low observability. The target characteristic signal is a set of characteristics that describes a type of weapon system that can be easily detected, including six kinds of characteristic signals of electromagnetic (mainly radar), infrared, visible light, sound, smoke and wake. According to statistics, 80 to 90% of aircraft losses in air combat are due to the observation of the aircraft. Reduce the platform characteristics of the signal, it reduces
