AWR1843BOOST: Does AWR1843BOOST radar module gives Width & Height Information of object?

Hi Vipul,

1. Object Width and Height Information
The AWR1843BOOST radar does not directly output the physical width or height of a detected object.
The demo application transmits detected points with parameters such as range, Doppler (velocity), and 3D spatial coordinates (x, y, z) through the MMWDEMO_OUTPUT_MSG_DETECTED_POINTS message.
Since each detected point represents a radar reflection (scatter point), not a full object contour, width and height are not computed or available as direct parameters.
If required, the approximate object dimensions can be estimated at the application layer by:
• Collecting all detected points (x, y, z) belonging to a single object
• Applying a clustering algorithm (e.g., DBSCAN or K-means)
This post-processing can be performed on the host side using the detected point cloud data.

2. Number of Data Points per Object
In each output frame, multiple detected points may correspond to a single physical object.
This is because the radar may receive multiple reflections from different parts of the same object’s surface.
Hence, the MMWDEMO_OUTPUT_MSG_DETECTED_POINTS message typically contains:
• Several points per object, depending on the object’s reflectivity and distance.
• Each point’s range, velocity, and 3D coordinates
If clustering or tracking is enabled on the host or radar processor, multiple points can be grouped and tracked as one object.

More information about the demo can be found in the docs folder of the SDK in the mmawave_sdk_module_documentation.html file.
