摘要
随着隐身技术发展,机载预警雷达主要作战对象的雷达散射截面积已经降低了一个数量级,现有机载预警雷达的探测威力已经不能满足军方作战需求。因此,充分利用载机平台外形、扩大雷达孔径的共形阵雷达将成为未来机载预警雷达的发展趋势。文中首先简述了机载共形阵预警雷达的特点,介绍了国外机载共形阵技术的发展;然后,通过仿真分析了共形阵最基本形式的方向图特性;最后,针对美国E-2这种小型上单翼螺旋桨飞机,分析了共形阵技术应用在这种载机上的可行性,指出了共形阵在这种载机上的一些问题。
With the development of stealth technology, the target RCS （ Radar Cross Section） of AEW （ Airborne Early Warning） has decreased an order of magnitude, and the detection range of existing AEW radar can not satisfy military need. Therefore, the conformal array radar that can use fully the fuselage of carrier platform and enlarge the aperture will become the trend of array AEW radar in the future. This paper firstly describes the architecture of eonformal array AEW radar, then introduces the development of airborne conformal radar in other countries, and elaborates the basic conformal type-circular array＇s pattern through simulation. Finally, it analyzes the feasibility of using the eonformal technology on small up-wing propeller plane like E-2 carrier and points out some practical problems of conformal array used on this kind of carrier.
