AWR1843: AWR1843 or IWR6843

Prodigy 10 points
Part Number: AWR1843
Other Parts Discussed in Thread: IWR6843,

Tool/software:

Company is going to develop system for special vehicles for detection of small radars  (30x30 cm) on a distance 100-150m.  The questions are:1. Do the  AWR1843 or IWR6843 are suitable for such usage? 2. Do those boards are able to detect targets by the following assumptions: - vehicle moving speed up to 60 km/h and drone flying speed  directly towards vehicle -up to 30 m/sec? What specification we need to order to deploy the system? What conditions will be affect  on radar performances' (rain, dust, fog????). How to order one radar with full installation manual  to provide testing?

    Hello,

    Thanks for posting your questions on E2E regarding radar usage for medium range detection vehicle and drone detection. I have looped in one of our ADAS engineers to look into this further, but it sounds like our Medium Range Radar (MRR) application may be a good starting point. Please take a look over it while you wait for a response from our ADAS engineers.

    Regards,

    Kristien

    Hi,

    Please note that the MRR demo was optimized for ADAS corner radar applications. We have not tested for drone objects. The detection range for vehicles is 120m.

    Please note that the demo is just a starting point. You will need to further customize the code for your use case

    thank you

    I wrote several questions and did not got full response. I really need to get radar for drone detection on a distance 120-150m. Once TI did not tested this application pls provide me the answers on the following questions: 1. Do you have internal calculation methodic to check if in principle radar will detect small drones ( 30x30cm) on a distance of 120-150m flying with the speed of 27 m/s towards radar? 2. Please confirm if antenna system have azimuth pattern of 120 degree ( we need this) and in elevation of 50-60 degree. 3. What components of 68 series with SW we need to purchase to provide own field test?

    Hey Anatolii,

    Sorry for the delay in response here. This thread ended up getting reassigned a few times before making its way back to me. See my comments below:

    I would recommend experimenting with the mmWave Sensing Estimator which allows you check different scene configurations and determine whether a viable device configuration can be achieved. However, based off the parameters you shared, it is very unlikely that the 1843 or 6843 will be able to detect drones at 120-150 m due to its low radar cross section (RCS). You might be able to start getting detections around 30-40m at best.

    This is dependent upon the antenna pattern you choose and what is considered an effective SNR response, but you can see the FOV and angular resolution for various devices at the following link: https://dev.ti.com/tirex/explore/node?node=A__AWIefc8Ua1PGb-npa25HjQ__radar_toolbox__1AslXXD__LATEST&placeholder=true

    For all xWR6843 and xWR1843 devices, the minimum FOV would be around ±60 degrees azimuth and ±15 degrees elevation. Our ODS and AOP boards achieve ±60 degrees for elevation.

    It's not completely clear to me the scope and depth of testing you're looking at doing here, but for software, you will need the MMWAVE-SDK for development. The MMWAVEICBOOST is also recommended for any non-BOOST boards if you would like to utilize CCS' debugging capabilities.

    If you are looking at building your own processing chain, we typically recommend customers obtain raw ADC data and use that for prototyping. This will require a DCA1000 and mmWaveStudio. 

    Hopefully this answers most of your questions or gives you a good starting point, but let me know if you have any other questions.

    Regards,
