无线电通信用发射和接收设备.光纤无线电技术及其性能标准.第3部分:用于异物碎片（FOD）探测系统的光纤无线电远程雷达

[中文适用范围]： IEC 63098-3 提供了远程雷达系统中连接中央站（CS）与远程雷达头（RRH）的光纤射频（RoF）接口的规范，以及确保供应商之间兼容性和选择适用于任何类型 RoF 系统以传输信号的必要信息。 [外文原描述]： IEC 63098-3:2022 This part of IEC 63098 provides the specifications of the RoF interface connecting the central station (CS) with the remote radar heads (RRHs) in a remote radar system, along with the necessary information to ensure compatibility between vendors and, hence, choose appropriate systems to cover any type of RoF systems for delivering the signal.A remote radar system generally consists of a central station (CS) and remote radar heads (RRHs) connected by radio over fibre (RoF). Each RRH has a maximum detection range of several hundred metres because millimetre waves theoretically undergo a larger propagation loss compared with conventional aeronautical frequencies below 10 GHz. The RoF system is key to enhancing the radar coverage and connecting the CS with the RRHs located along a runway for its entire coverage. To ensure the connection between the CS and RRHs, radio frequency (RF) and optical interfaces should be categorized according to their specifications, specifically, their link characteristics.
