AWR1843BOOST: AWR1843BOOST EVM - HELP TO REDUCE NOISE & INCREASE OBSTACLE DETECTION

Hi

With the AWR1843BOOST antenna, with MIMO ~50m would be the best performance you can achieve. Beyond this distance we see customers using beamforming & tracking. They also may have custom antennae.

In some of the snapshots such as Test13, it is difficult to understand that the large vehicle in front is not detected.

Is there another object detected at the same range?

Thank you

Cesar

Hi,

we are planning to have the max range to 50 meters only(but our inference is absolute 50 meter range obstacle detection doesn't happen in all scenarios)

Can you please let me know, if the increase of RCS in the Demo Visualizer would increase the range of obstacle detection?

Please find the other images(where there are no obstacles detected)

Following Object is detected at Long Range, but the long range detection is not consistent, Can you please help me make the obstacle detection consistent

Can you please help  me resolve this issue.

Thanks

Hi Cesar,

Please note, I have attached the Images.

Thanks

Hi,

As I mentioned, with AWR1843BOOST, using MIMO, the max range would be around 50m. For different type of objects the detection at 50m will not be robust.

To increase the robustness of the detection you will need to use the max possible chirps in your configuration. I have reviewed the chirp configuration used and right now it does not have sufficient chirps. However even with more chirps we expect that there will be some challenges detecting some objects at 50m with MIMO

Thank you

Hi Cesar,

Thanks for your response.

Please find the attached Chrip Configured using DEMO VISUALIZER

Can you please let me know, if we can edit the Config file to increase the Chrip Value, Is there any way to increase the Chrip Value again?

I understand, Not all objects can be detected at the range of 50 Meters, the most necessary thing for us is Obstacles like Motorbikes or Bicycle or Pedestrians shall be detected at the range of atleast 20 Meters, In order to slow down the Host Vehicle to avoid Collision.

Can you please guide me to get the best possible detection of all Obstacles at the distance of at least 25 to 30 Meters. 

Thanks

Hi Cesar,

Can you please respond to my queries.

Thanks

Guru

Hi,

Please give me some time to review your questions

thank you

Cesar

Hi Cesar,

Sure. Thanks. 

Hi Cesar,

Thanks for your response.

We will try the MRR demo ,as we have only tried to create our own config file using the MMWAVE demo visualizer.

We will use the config file shared by you and share you the results next week.

Thanks

Guru

Hi Cesar,

Good Day!

Thanks for your response, We are currently testing the Config file shared by you, using AWR1843BOOST EVM, I will get back to you with the results post analysing the test results.

Regards

Guru

Please try to use also the MRR demo and compare the results.

Thank you

Cesar

Yes Cesar. I will capture and compare both the results, analyze and let you know the full picture.

Thanks

Guru
