摘　　要：无线电测向历史悠久，在民用和军用领域得到了广泛应用。该文通过对幅度比较式测向原理的分析，推导出基于正交双环形天线的改进型沃特森一瓦特测向算法，同时给出在MC3362上的硬件实现方法，最后由理论与实测结果的对比，进一步剖析算法特点及使用注意事项。该算法具有易实现，操作简单，搜索速度快等特点，适用于快速测向手持设备。Radio direction-finding has a long history and have been widely used in many civil and army domain. Through analyzing the principle of amplitude-comparison direction-finding, this paper deduces an improved Watson-watt direction finding algorithm based on orthogonal stacked loop antenna.And the hardware method on MC3362 is also given.Finally, the advantages and the caution of usage are all given through comparing the theoretically and measured results. This algorithm has many advantages such as easy realization, simple opera- tion, rapid searching, suitable for quick direction-finding handheld devices.
