摘　　要：目前,我国现役测风仪器,大多采用机械旋转式传感器。由于它存在转动惯性,难以测到风的瞬时变化值。另外,由于结构特点,其使用受到一定的限制。针对这一现状,本文根据世界气象组织(WMO)推荐的测风新技术- 压力正交测风技术,采用固态硅压阻压力传感器设计了一套新型测风仪,并介绍了其软、硬件的实现。The wind detecting instruments of PLA on duty are almost mechanical rotary type sensors. Because of moment of inertia, It could not get the instantaneous changes of the wind vector. Secondly, the mechanical structure characteristics of the rotary type sensors limited its usage in some environment. According to such situation, this thesis discuss the development of a new kinds of wind detecting instrument using solid state silicon piezoresistive pressure sensors, which the WMO recommend. And we developed a sample of solid state wind detecting instrument, introduced its realization in both software and hardware.
