罗马航空发展中心,西屋公司和其它一些航空公司的研究人员正在研究将光导纤维应用于相控阵雷达天线。 先进的机载雷达天线可能有1000～10000个有源阵元,每个阵元必须用微波元件和同轴电缆连接。但微波电缆在相控阵雷达成本中占据了很大部分。另外同轴电缆的体积和重量都较大,这样便加重了空中和陆地移动装置的负荷。相比之下,采用光导纤维电缆来连接相控阵雷达天线的阵元,不仅便宜、轻便而且能够传递更多的信息。因此,它是一个很有吸引力的选择方案。
Researchers at the Rome Aviation Development Center, Westinghouse and several other airlines are studying the application of optical fibers to phased-array radar antennas. Advanced airborne radar antenna may have 1000 ~ 10000 active array elements, each array element must be connected with microwave components and coaxial cable. However, microwave cables account for a large part of the cost of phased-array radar. In addition coaxial cables are bulky and heavy, which adds to the load on air and land mobile devices. In contrast, the use of fiber optic cables to connect array elements to phased-array radar antennas is not only cheap, lightweight, but also delivers more information. Therefore, it is a very attractive option.
