AWR6843AOPEVM: AWR6843AOPEVM vs AWR1642BOOST-ODS vs AWR1642BOOST

Part Number: AWR6843AOPEVM
Other Parts Discussed in Thread: AWR1443BOOST, AWR6843AOP, AWR1642BOOST-ODS, AWR1642BOOST, AWR1443, IWR6843AOP, IWR6843, IWR6843AOPEVM

I have a unique application to track a reciprocating pump piston rod at close proximity from 20cm to 30cm. Piston rod has a Stroke Length of 30cm with 1 to 240 Strokes Per Minute (SMP) - i.e. a maximum linear speed 0.01m/s to 2.4m/s, but the motion is complex with sinusoidal acceleration and speed, field of view 90 to 120 degrees. With the evaluation of AWR1443BOOST for the application, I have concluded that to track the piston rod at low SPM (1) further processing power and algorithm development is required with a DSP as the pump enclosure is made of metal (Steel) as well. i.e. grouping of objects feature will be required to tweak

About 60 Strokes Per Minute with AWR1443BOOST

I am considering to use one of the following to evaluate further and would like to make sure the hardware is suitable for the application:

AWR6843AOP EVALUATION BOARD
AWR1642BOOST-ODS
AWR1642BOOST

I need some expert advise / guidance in selecting one of the above module. However my preference is AWR6843AOP as it will make the design of production PCB much simpler.

Hello

Thank you for your interest in mmWave Sensors. Seems like you have already used the AWR1443 based EVM and have an idea of how the response from sensor looks. Is that correct?

About Selecting right mmWave Device :

Our AWR series of sensor are targeted towards Automotive ADAS applications, while the IWR sensors are meant for non-ADAS applications that span Industrial and Home Automation and In vehicle sensing applications ti.com/IWR. The IWR6843 and IWR6843AOP use the ISM frequency band which are allowed by most regulations for such applications.

Please the available similar applications and accompanied example software demo/labs here:

You may want to Try the IWR6843AOP (IWR6843AOPEVM) to try an evaluate for the application.

Hope that helps.

Thank you,

Hi Vaibhav,

Thanks for your reply.

Could you please explain the pros and cons of frequency reduction from 77GHz to 60GHz for the IWR sensors?

Are there any performance advantages by reduction in the frequency or it is purely to satisfy regulatory requirements?

Regards

Vithy

Hello

Regulatory is the major factor. Please look at the EM spectrum properties on the web to understand the interaction differences based on the frequency value.

Thank you
