请问,
1、mmWaveStudio中SensorConfig配置chirp时,左图中的Chirp Start Index有什么意义和影响? 比如左图中第一行RX0从第三个Chirp开始到最后第15个Chirp结束。
2、这第3到15个chirp之间的那些chirp是按照什么样的顺序发送的?
3、SensorConfig配置Frame时Start Chirp TX和End Chirp TX的意义和影响是什么?按照右图中的配置是指第0个天线开始发送Chirp到最后结束时也是第0个天线发送chirp吗?

1. Chirp Start Index表示第一个chirp号,Chirp End Index表示最后一个chirp号. 您的理解正确。这些chirp有同样的参数如ProfileId, StartFreqVar, FreqSlopeVar, IdleTimeVar, ADCStartVar等。2. 按照chirp3->chip15顺序发送3. 请参考下面的帖子,讲得比较详细。https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/655105/awr1642-capture-demo-configurationhttps://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/801694/dca1000evm-how-to-use-the-start-chirp-for-cfg-and-end-chirp-for-cfg-in-chirp-sub-tab-how-to-use-the-start-chirp-tx-and-end-chirp-tx-in-frame-sub-tab

感谢回复,看了您发的帖子,已经理解了。不过对于官方视频中提到的complex1X和complex2X的解释,还是不太理解,原文是这样说的,In case of the complex 1x, the front end filters out the image band, whereas in the case of complex 2x, both the image band and the inband is sent out. Since in the case of the complex 1x, the image band is filtered out, and since the image band contains the interference information, the mmWave front end can also construct this information in the form of a separate packet, which we call the chirp quality, or CQ. So the front end can be configured to receive the CQ data, as well.
请问,
1、文中提到的image band翻译成中文应该怎么理解?
2、complex1X和complex2X的区别具体是什么?
