Abstract

The invention discloses a waveguide beyond-visual-range wave monitoring radar which is provided with a sensor unit for measuring hydro meteorology data and further provided with a waveguide computation module, a beyond-visual-range estimation module and a wave monitoring module. The waveguide computation module is used for computing whether sea surface evaporation waveguide is provided or not under the current meteorological condition, and the beyond-visual-range estimation module is used for judging whether the radar has beyond-visual-range performance or not under the current meteorological condition. The wave monitoring module is used for delimiting isometric grids in the any direction of the detection range of the current radar under the sea surface evaporation waveguide, recording radar echo intensity of each grid, removing strong signals of the sea surface targets, keeping weak signals of the sea clutter in the echo, judging that a plurality of grids are crest, wherein the intensity of the weak signals of the sea clutter in the echo is larger than that of the periphery grids, obtaining echo signals of all wave crests in the scanning area, obtaining the lengths of the adjacent crests, namely the wavelengths, recording the scanning period of two adjacent radars, obtaining the movement direction, the movement distance and the movement speed of the wave, computing the wave frequency and completing the wave monitoring.

Description

technical field [0001] The invention relates to a waveguide over-the-horizon ocean wave monitoring radar, in particular to an over-the-horizon radar system for monitoring ocean waves through ocean wave echoes under the condition of sea surface evaporation waveguide. Background technique [0002] Ocean waves are one of the important physical parameters in the ocean, which have a great impact on ships and offshore operations, even fatal. Ships sinking, casualties, offshore structures, and coastal structures are damaged every year due to strong winds and waves all over the world. As human activities march toward the ocean, monitoring and early warning of large storms has become an unavoidable practical problem. This invention is just proposed for human disaster reduction and resistance to natural disasters, and has important practical significance and market prospects. [0003] The X-band navigation radar is selected as the wave parameter measuring instrument, which has high ...
