摘要
Abstract
Ultrasonic level wind measurement technology has been used in the meteorological observation business for many years ,which achieves good effects .The flat triangular configuration will be transformed into the tetrahedron structure ,and then it forms a special structure with three‐dimensional measurement capability .The design uses stepping frequency measurement technology to emit the ultra‐sonic frequency of 100 kHz to spread spectrum modulation .After receiving the data ,the design obtaines the pulse compression ,it has solved the following two problems :the lower peak transmit power's receiver sensitivity and the measuring time accuracy causing by the ultrasonic pulse .It also has the anti‐jamming capability .The feasibility of this method is confirmed by the simulation and laboratory ex‐periments .关键词
