Abstract:
At present, China has made a lot of creative works in the field of automatic cloud observation, independently developed a full solid state and coherent dual liner polarization of millimeter wave cloud radar. This paper introduces the detection capability of the radar mainly from the parameters of radar system and the key technology, and extracts the ra- dar base data to further analysis the reliability of the detection ability of the millimeter wave cloud radar, by combining with instances from the perspective of data processing. The main conclusion to be draw from this paper are the following: (1) the millimeter wave radar basically meets the requirement of the cloud observation service, and gets the meteorologi-cal data products such as echo intensity, vertical velocity, velocity spectrum width, cloud and so on. Also, it can reach more than 10 km altitude in detection range and reach 30m in vertical resolution. (2) Millimeter wave radar is capable of obtaining the cloud of basic information, including the cloud height, cloud cover and cloud thickness and cloud varie- ty, which can provide reliable data and information in other areas of research. (3) The adaptability of millimeter wave radar for different types of weather conditions is strong. In rainfall weather conditions, the cloud particles within the echo intensity change can be obtained, providing good support for the development of cloud prediction and cloud research of macroscopic properties (to the mutual evolution between different clouds). Also, the emission of electromagnetic waves by millimeter wave radar is less affected by fog, haze and other weather phenomena. It can penetrate clouds and obtain information about the internal cloud structure to grasp the cloud vertical structure. Finally, the detection ability of the millimeter wave radar is summarized and the future research direction of millimeter wave radar in China is prospected.
