Radar data is extremely sparse - not HD #4

Hi,

I had the idea that the radar used was high definition and should given a much denser point cloud than conventional radars. However, I see the point clouds are very sparse as seen below.

1) Lidar image

2) Radar - Front image

Am I doing something wrong here? Please explain this.

Best Regards Sambit

Hi @SM1991CODES,

We used SmartMicro UMRR-11 during the recordings of the dataset, which is not a high-definition radar. Its output is sparse (<100 data points/scene), but we found it beneficial in long-range detections and in adverse weather (e.g., rain).
