摘要
在原UWB多目标异步定位及其算法的基础上,针对其存在的问题提出改进算法。在保持原一般性的情况下,实现剔除冗余测量的目标。采用帧多次往返测量法和相互测量法,实现全部差分测量,改进了测量误差分布特性。提出递进测量新概念应用于超宽带异步测量和定位,较好的协调了测量速度和精度的关系。选用优化算法,很好地解决了定位方程的求解问题。仿真结果说明,方法有效可靠,性能稳定,适于实际应用。
Based on the asynchronous localization method and its algorithm presented for multiple targets, the improving method was proposed for its problems. Under the instance retaining the universality, the goal to remove the redundant measuring was achieved. With the method of the frame round-trip transmission （RIT） multi-times and measuring reciprocally, the difference measurement was realized entirely, and the distributed characteristic of the measurement error was improved. Bringing the concept of progressive approach into UWB measurement and localization, the relationship between speed and precision of measurement was harmonized preferably. The problem of localization equations system method was solved commendably by using digital optimization algorithm. The validity, reliability, practicability and stability of the method are proved by simulation results.
