请问有人走通 PDOA, AOA 的吗?

我用官方代码走通了,但是结果不准,不管使用x y 还是距离角度, 跳变都比较大。有人知道是怎么回事吗?

没有哦,你能共享下相关资料吗?

这个是官方文档里面的内容,

After calibration is applied. Approximately +/-15cm without calibration.
2 Ranging standard deviation is measured at -85 dBm power level.
3 Note: in a typical PDoA based system the computed angle of arrival (AoA) accuracy is better than the PDoA accuracy by
a factor of approximately two i.e. if PDoA accuracy is ±10° then AoA accuracy is ±5°.
4 For optimal PDoA performance a crystal offset of greater than |5| ppm is required between devices.

从这里面看, AOA 模式确实精度会高一些, 但是厂家放弃了这种模式,在DW3000 里面,匪夷所思
