MMWAVE-STUDIO: More than 256 doppler chirps

Part Number: MMWAVE-STUDIO


Hello,

Some of these questions have been covered in the User-Guide and the training video but they havnt been described in depth. 

  • What is the functionality of the 'Start Chirp for Cfg' and 'End Chirp for Cfg' in the Sensor Configuration section 3.2

  • In the below example I have set the Start Chirp for Cfg to 0 and End Chirp for Cfg = 500 with only one Profile Id= 0 and the 'number of Chirp Loops' = 4 (Section 3.3), which I would think result in 501*4 = 2,004 chirps in a frame, hence there should be 2048 doppler bins

 

  • But this is not true in the DSP Post processing example given in the mmwave studio demo, attached below. How does the number of TX Channel depend on the Chirp Config and number of Doppler Chirps depends only on the Number of Chirp Loops.
