标准范围

ISO 19926-1:2019规定了使用2 GHz至10 GHz频率测量大气的地面天气雷达系统的系统性能。这些系统适用于在不同高度的区域范围内探测降水和其他气象目标。本文档还描述了验证系统性能不同方面的方法，包括基础设施。ISO 19926-1:2019适用于线极化抛物面雷达系统、双极化和单极化雷达。它不适用于扇形波束雷达[方位角窄（AZ）和仰角宽（EL）]，包括用于但主要不是为天气应用而设计的海洋和航空监视雷达。具有电子成形和定向波束（包括多波束）的相控阵雷达，具有非圆形离轴瞄准模式，是一种新的雷达，可用的性能信息不足。ISO 19926-1:2019没有描述天气雷达技术及其应用。天气雷达系统可用于定量降水量估算（QPE）、水文气象物分类（如冰雹）、风速估算以及严重气象现象（如微暴流、龙卷风）的检测和监测等应用。其中一些应用对雷达系统的定位有特殊要求，或需要特定的测量策略。然而，本文件中描述的校准和维护程序也适用于此处。ISO 19926-1:2019涉及制造商和雷达操作员。

ISO 19926-1:2019 specifies system performance of ground-based weather radar systems measuring the atmosphere using frequencies between 2 GHz and 10 GHz. These systems are suitable for the area-wide detection of precipitation and other meteorological targets at different altitudes. This document also describes ways to verify the different aspects of system performance, including infrastructure.ISO 19926-1:2019 is applicable to linear polarization parabolic radar systems, dual-polarization and single-polarization radars. It does not apply to fan-beam radars [narrow in azimuth (AZ) and broad in elevation (EL)], including marine and aeronautical surveillance radars, which are used for, but are not primarily designed for, weather applications. Phased-array radars with electronically formed and steered beams, including multi-beam, with non-circular off-bore sight patterns, are new and insufficient performance information is available.ISO 19926-1:2019 does not describe weather radar technology and its applications. Weather radar systems can be used for applications such as quantitative precipitation estimation (QPE), the classification of hydrometeors (e.g. hail), the estimation of wind speeds and the detection and surveillance of severe meteorological phenomena (e.g. microburst, tornado). Some of these applications have particular requirements for the positioning of the radar system or need specific measurement strategies. However, the procedures for calibration and maintenance described in this document apply here as well.ISO 19926-1:2019 addresses manufacturers and radar operators.
