Doppler velocimeter windshield

The invention provides a Doppler velocimeter windshield which comprises a regular polygon-shaped fixing frame, each vertex of the fixing frame is provided with a floater, and each floater is connectedwith a fixing base through a plurality of elastic fixing ropes. A top cover is arranged in the center of the fixing frame, the periphery of the top cover is connected with a wave absorbing side skirtthrough a wind shielding side edge, and an open hole is formed in the middle of the top cover. The wave absorbing side skirt comprises a skirt tip, an outer wave absorbing fence and an inner wave absorbing fence which are sequentially arranged from outside to inside, and the outer wave absorbing fence and the inner wave absorbing fence are each of an annular fence structure and are arranged in astaggered mode. The Doppler velocimeter windshield has the advantages that wind-induced flow on the surface layer of the water body is filtered out through a physical method, and the measurement accuracy of the section flow velocity of the reflection-type Doppler velocimeter is improved.
