使用AWR2243四芯片级联,自制雷达前端板,天线尺寸20cm左右
使用角反射器校准相位时,角反射器与天线的距离有什么要求?目前发现在不同距离校准得到的通道之间的相位差变化较大,选多远的距离比较合适呢?

抱歉回复晚了。
我们用的不是EVM,是自研板,尺寸要更大,有20cm
对于20cm的自研板来说也是一样的,建议用3-5m。
以下为工程师的答复:
"Calibration can be performed with specific chirp configuration.
If you want to use 40m, this is fine.
If you want to use 3-5m, maybe it needs to update the configuration."
