摘　　要：针对小型飞行器无线电地面定位系统的指标要求,设计出一种数字化高精度角位移传感器。介绍了角位移传感器的系统组成与原理设计,通过分析选择了以旋转变压器作为角位移采集器的设计思路,给出了角位移传感嚣的硬件设计,并详细论述了软件设计中的数据采集与数据处理方法。通过对系统进行实验室静态测试和飞行过程动态测试,其测试结果与固定方位角或GPS数据拟合良好。误差分析表明:给出的角位移传感器设计合理,精度满足系统指标要求,可推广应用于其他领域的角位移测量系统。According to the requirement of wireless ground-locating system for small aircraft, a high-precision digital angular sensor is proposed. The structure and the principle of angular sensor are introduced, resolver is selected as angular collector through analysis and the hardware design and the way of data collection and processing is expatiated. Through the static test in laboratory and the dynamic test during fly the result fits fited orientation angle or the data of GPS well. The analysis of deviation shows that the angular sensor is feasible and could be popularized to angular-measuring system in other fields.
