IEC 63098-3:2022 IEC 63098的这一部分提供了远程雷达系统中连接中央站（CS）和远程雷达头（RRH）的RoF接口规范，以及确保供应商之间兼容性的必要信息，选择合适的系统来覆盖任何类型的RoF系统以传输信号。远程雷达系统通常由通过光纤无线电（RoF）连接的中央站（CS）和远程雷达头（RRH）组成。每个RRH具有几百米的最大探测范围，因为与低于10GHz的常规航空频率相比，毫米波理论上经历更大的传播损耗。 RoF系统是增强雷达覆盖范围并将CS与位于跑道沿线的RRH连接起来以实现整个覆盖范围的关键。为了确保CS和RRH之间的连接，射频（RF）和光接口应根据其规范进行分类，特别是其链路特性。

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.
