MMWCAS-RF-EVM: FOV for the Image mmWave Radar

Yu Zhang

Part Number: MMWCAS-RF-EVM

Hi team,

Referring to the document "Imaging Radar Using Cascaded mmWave Sensor Reference Design", it mentions that the Antenna field of view ±70 degrees with an angular resolution of approximately 1.4 degrees for the MMWCAS-RF-EVM.

So, does it mean that the Horizontal and Vertical views are the same ±70 degrees? What about the Diagonal view?

Please advise FOV in the form of DxHxV.

Thanks.

Hello Zang,

You could refer to below EVM user guide.

https://www.ti.com/lit/ug/swru553a/swru553a.pdf

Antenna has gain in the elevation direction hence it's field of view would be narrow i.e. ~+/-20 Deg. Azimuth field of view is +/-70 Deg.

Below is the polar plot representing Azimuth cut and elevation cuts.

3D view of Azimuth and elevation pattern.

Thanks and regards,
