IWR6443: Possibility for narrow range

Hi,

This question may be simpler to answer with more context on the exact intended use case. There are many tradeoffs that may be acceptable depending on the usage, so more context is very beneficial. If you do not want to share this on the public forum, let me know and we can move this discussion elsewhere. 

To respond to your questions directly:

1. You ask about a range of 2°, are you referring to angular FOV? I do not understand the unit chosen here in regards to range.
2. Are you referring to the accuracy of the position of detections in 3d space? or are you referring to a specific dimension?
3. I assume you are referring to the pcb space? Our smallest form factor by far is the IWR6843AOP devices, I would need to discuss with our Hardware teams what the smallest form factor would be for a 6443 solution, but this would likely be dependent on antenna layout needed as well.

Hello Alec-san

Thanks for your reply.

1. Yes, FOV is 2°

2. I want the accuracy about object distance measurement.

3. Could you let me know the pcb space? It is enough information based on TI EVMs.

This stage is in very early estimate stage.

So, I don't many information about the concept so far.

Hi,

1. FOV could be reduced by software (ie ignoring points detected outside the FOV, however if they want to reduce the physical area which the radar detects then they would likely need a lens. A lens can be used but can have significant impact on the algorithm. 

2. For most of our labs, the smallest range resolution is 4cm. However, if you take a look at the High Accuracy Level Sensing lab, it has an accuracy of less than 1mm. This comes with some constraints, such as not providing any angle information, only a range. 

3. I will allow my colleagues to comment here.

Best Regards,
Alec
