基于软件无线电技术的水下平台姿态采集系统设计

根据水下晃动平台进行目标高精度探测、定位、跟踪的需要，引入平台姿态估计系统，讨论了平台坐标系与大地坐标系的转换关系。应用软件无线电技术的基本设计思想，选择适于长期自主工作的姿态传感器件，设计了具有软件无线电结构的采集系统。最后，构造平台姿态采集系统样机，验证了设计功能的可行性。

Attitude Data Acquiring System Design for Underwater Platform Based on Software-defined Radio Technology

The underwater platform rocks constantly in the water, which will lead to serious bias in the long -range detection of the target. Therefore, it is necessary to track and predict the attitude of sway platform accurately. A attitude data acquiring system is designed. This system is constructed with the internal structure of software - defined radio technology, which can work autonomously long time based on one low power - consumption electronic compass. Finally, the functionality that change sampling mode in dynamic condition has been verified with the prototype of data acquiring system.
