MMWAVE-STUDIO: what does the PostProc result: "ADC data vs doppler FFT output" means?

Part Number: MMWAVE-STUDIO
Other Parts Discussed in Thread: IWR1642

Hi.

I have some confusion about the PostProc result of the mmWave studio (version: 02.01.01.00, Device: IWR1642). What does the result of "ADC data vs doppler FFT output" means? What is the difference between the result of "2D FFT amplitude profile" and the "ADC data vs doppler FFT output"? Because I notice that there are some differences between them but I don't know how to get the result of "ADC data vs doppler FFT output".

Thanks.

HI,

Please check the radar studio User guide located at: C:\ti\mmwave_studio_02_01_01_00\docs\mmwave_studio_user_guide.pdf. You should be able to find some information there.

Best,

I have done as suggested. But there is nothing about the "ADC data vs doppler FFT output".

HI,

Range-Doppler Amplitude output is the one we usually use. I have never used ADC data vs. Doppler output before. But by looking at your figure and the name, it should mean the Doppler FFT on top of ADC data, i.e., FFT cross chirp for each ADC sample. It will show a change over chirp for time domain data.

Best,

Zigang
