Other Parts Discussed in Thread: DCA1000EVM, UNIFLASH
在8cm处有一个目标,但是实际上什么都没有,如下图所示。但是和MMWAVE ICBOOST以及DCA1000EVM一起使用,通过mmwave studio软件采集时就不会有这个假目标存在

结合ICBOOST和DCA1000EVM测得的回波就不会有这个假目标
能否把这个图发出来看一下。
你好,
我建议调节的HPF就是抑制近处目标的。你看到的不同现象是因为两个配置的最远距离不同,这个目标在两个配置的中频里的频率不同,所以HPF抑制也有所不同。下面的论坛讨论请参考:
IWR6843: filter order/frequency response - Sensors forum - Sensors - TI E2E support forums
你有做过校准么?校准后现象有变化么?
你好,
图上最后抬高,可以忽略相关信号。
Typically, the IF frequency range preserved well in the receiver baseband is 0.9 × Sampling Rate in Complex 1x and 0.45 × Sampling Rate in Complex 2x and Real/Pseudo Real.
你好,

这个参数是如何设定的?
