Embodiment

[0061] Embodiment: The millimeter-wave radar measures the sea area between the coastlines on both sides of the millimeter-wave radar, and sets the radar to perform a sectoral scan in PPI mode between A1 and A2 at a pitch angle of 3 degrees. The speed of the clockwise scan is set to 0.4 degrees / second, the speed is set to 0.6 degrees / second when scanning counterclockwise, and for each round-trip cycle of scanning, do a RHI scan with a scanning speed of 1 degree / second between the pitch angles of 0 degrees and 30 degrees, and scan to get The data sent to the terminal server, the terminal server determines the reference time, the difference between the detection time of the cone detection data obtained by the PPI mode sector scan and the reference time is arranged in ascending order, and the two groups of cones in the first two positions are selected Detection data, that is: extract two sets of cone detection data whose detection time is closest to the reference time in the cone d...

Abstract

The invention relates to a harbor navigation channel sea fog detection method and system for millimeter wave radar devices. The system comprises at least two millimeter wave radar devices and a terminal server, wherein the millimeter wave radar devices are used for carrying out repeated scanning in a pre-determined scope to acquire multiple sets of cone detection data and multiple sets of vertical detection data and sending the multiple sets of cone detection data and the multiple sets of vertical detection data to the terminal server, and the terminal server is used for processing and displaying the data. The system is advantaged in that networking observation of the multiple millimeter wave radar devices is realized through pertinent data processing methods and fusion means, a coverage scope of the sea fog monitoring system based on the millimeter wave radar devices is effectively expanded, and the higher practical application value is realized.

Description

technical field [0001] The invention relates to the field of radar detection, in particular to a method and system for detecting sea fog in a port channel based on a millimeter-wave radar. Background technique [0002] The port is an important hub of maritime traffic. However, due to the high humidity at sea and the unpredictable weather, the port channel area is often covered by sea fog. The low visibility caused by sea fog will seriously affect the efficiency of port navigation, and pose a great threat to the traffic safety of ships operating in the channel. At the same time, it puts forward higher requirements for port dispatch management. Because sea fog has the characteristics of fast formation / dissipation, wide spatial distribution area, low height, and weak electromagnetic wave echo intensity of water vapor particles, traditional visibility instruments, fog droplet spectrometers, weather radars, satellite remote sensing and other means have a large impact on sea fog. ...
