AWRL1432BOOST: numOfChirpsAccum parameter in frameCfg

Liam

Part Number: AWRL1432BOOST

Hi experts,

In the following link: frameCfg numOfChirpsAccum parameter, I have known the information that if I configure the frameCfg 128 2 4000 1 100 0, the chirps that will be processed will be 128/2 = 64 chirps.

I have two questions,

1. Whcih mode does this numOfChirpsAccum can be used, the normal mode or both the normal mode and burst mode?

2. How is the numOfChirpsAccum affects the doppler resolution or max velocity? Here I am using the normal mode, so I didn't find difference in doppler step.

Regards

Liam

1. It should be possible to use this for all modes

2.If in your configuration number of burst=1, the doppler step calculation will only use number of gMmwMssMCB.frameCfg.h_NumOfChirpsInBurst. This is picked up from the cfg and remains 128

When using numOfChirpsAccum the max-velocity would reduce by a factor of numOfChirpsAccum

The ‘effective’ doppler step will decrease by c_NumOfChirpsAccum factor if the chirp accumulation feature is used

hi ,你好，我们也想用1432的demo板做采数用，但是目前没调通，都有哪些步骤设置mmwavestudio能够用DCA1000采数成功呢？请多指教，谢谢

hi, hello, we also want to use the 1432 demo board for data collection, but there is no tuning at present, what are the steps to set the mmwavestudio to successfully use DCA1000 data collection? Thank you for your advice。
