Embodiment

[0131] Such as figure 1 As shown, the radar host 2 transmits electromagnetic wave signals to the dual-polarized antenna 1, and the dual-polarized antenna 1 scans the sea surface at 360°, and simultaneously receives the scattered radar signal from the sea surface, and displays the unidentified signal through the display 4 connected to the radar host 2. After processing the radar clutter video signal, the radar video data and azimuth information are digitally stored in the storage unit 12 (disk array in this example) through the data acquisition module 5 . The radar PPI (Plane Position Indicator) image is imaged and the wave parameter information is displayed through the radar data processing program. The dual-polarized antenna 1 is erected on the shore, and the dual-polarized antenna 1 and the scanning area are required to be unobstructed and the wind speed is greater than 3m / s.

[0132] Such as figure 2 As shown, the video signal of the radar sea surface echo is converted i...

Abstract

The invention discloses a dual-polarized X-wave band radar ocean wave parameter measurement system, comprising a radar, wherein the radar consists of a radar host and a dual-polarized antenna which isconnected with the radar host in a communicated manner; the radar host is connected with a data acquisition module of a computer; the data acquisition module converts video signal output by the radarinto digital signal and stores the digital signal in a memory unit of the computer; the computer is connected with a polarized switching control module by an I / O interface and is connected with the dual-polarized antenna by the polarized switching control module in a control manner; one end of the dual-polarized antenna is connected with the radar host in a communicated manner, and the other endthereof is connected with the polarized switching control module. The system can provide off-shore area ocean wave parameter information for all day in real time accurately, with the characteristics of security and non-easy lost, low maintenance cost, stable and reliable work, simple and easy operation, and can observe for a long term, therefore, the invention has good application value and marketprospects.

Description

technical field [0001] The invention belongs to the field of marine dynamic element monitoring, in particular to a dual-polarization X-band radar sea wave parameter measurement system capable of real-time collection of sea wave data and real-time provision of sea wave parameters. Background technique [0002] Ocean wave is one of the important physical parameters in the ocean, which is of great significance to marine engineering construction, military activities and oceanographic research. According to its observation method, ocean waves can be divided into two methods: traditional on-site direct observation and remote sensing observation. On-site observation, such as floats, buoys, etc., which directly contact seawater to measure wave parameters, has the disadvantages of single-point measurement and limited observation range. Compared with traditional on-site direct observation, remote sensing observation has advantages such as large observation range, but it also has corr...
