The generated radar point cloud from raw ADC data is sparser #54

Hi,

Thank you for your amazing work!

I have a question about reproducing the "ready to use" data from the raw ADC data. I could reproduce exactly the same image and LiDAR point cloud, but the radar point cloud would be sparser. Take the first frame, 000018, as an example, your provided ready to use data has 1000+ radar points. However, I used your provided radar signal processing code, and generated only 700+ radar points. I thought it may due to the code you released is not the same as you actually used to generate the ready to use data. If so, could you please update the radar signal processing code you actually used?

Thank you in advance!

Hi, thank you for your message.

I have met the same question. I found the 'ready to use' radar point cloud is sparser, and also, the azimuth and elevation angle seems 50-60 times larger than the one we produced by the signal processing example pipeline.

Do you have any idea about it or have you figured it out?

Thank you in advance!

Do you have the original ADC data of RADIAL?

hi, the raw data is not available in google drive now, can you share it with me via some ways? thanks!
