AWR1642BOOST: AWR1642BOOST or AWR1843AOPEVM

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1843AOPEVM, AWR1843BOOST, , IWR1843BOOST, IWR1843, AWR1843, AWR1642

Tool/software:

Hi. We are developing a prototype on general purpose radar and camera fusion technology for autonomous driving, surveillance etc as a student project. Since this involves combining outputs of the radar and camera, the angular resolution of the radar has to be decent, therefore AWR1642BOOST with the SRR demo capable of achieving 15 degrees resolution using USRR mode would be most suitable. By modifying the MRR demo to only use MRR mode for the AWR1843AOPEVM, angular resolution would be around 28 degrees. May I know if there's any work in progress to enable USRR mode on the AWR1843AOPEVM to achieve better angular resolution? On the other hand, AWR1843BOOST with good range and angular resolution would be ideal but there's no stock on TI as of now and the price of buying from other distributors is quite high for us.

    Currently there is no plan to update MRR demo SW offering.

    Can you share the screenshot where it says the device is out of stock?

    On the product page, it says Inventory: In stock and I was able to add it into cart. But during checkout, I was stuck at Regulations and it shows this

    Yes, the product is currently out of stock. You can click on "Notify me when available" to know whenever AWR1843BOOST EVM is available.

    Hi. I just found out about IWR1843BOOST, and everything about it seems to be identical to the AWR1843BOOST except the automotive certification and junction temperature range.

    1. Can the IWR1843BOOST run the MRR demo that is written for AWR1843BOOST with the same performance?

    2. Is the IWR1843BOOST capable of running SRR demo? Because from the demonstration video here https://www.ti.com/tool/AWR1642BOOST, SRR demo seems to be more robust/lesser noise compared to https://www.youtube.com/watch?v=VzWBpSuRFiM

    Yes, you should be able to run MRR demo on IWR1843 with same performance as AWR1843.

    SRR demo is developed using AWR1642. You can make changes to the demo to make SRR run on 1843. But it's advised to use MRR demo with AWR1843. Since the scenario is different in both the videos, you cannot compare the performance of both the applications. In MRR demo video, you can observe tunnel, flyovers etc. When you pass through tunnels, you might observe much noise when compared to driving on normal roads. SRR demo video is captured in environment with less noise (no tunnels, no flyovers). SRR processing chain is mostly similar to the processing chain of MRR demo. Main difference is that, in case of MRR (AWR1843) you have 3Tx antennas (1 elevation Tx antenna). Whereas SRR demo (AWR1642) has only 2Tx antennas (no elevation antenna).
