| 中文摘要 | This paper presents the development of the miniature airspeed meter and barometric altimeter with high resolution, high accuracy, small size and low weight. A microprocessor is applied to control the AID converter, set the digital potentiometer, filter the signal and calibrate the result. The low-pass filter in the analog circuit cuts off most of noise such as electromagnetic noise. The digital signals are modeled as 1-order AR processes. Based on the AR model, a Kalman filter is implemented to achieve optimum estimation. The whole device, including circuit and pitot tube, only weighs less than 10 grams. It can be widely applied in the fields of airplanes, vehicles, outdoor sports, and etc. |
