Other Parts Discussed in Thread: AWR1843
Hi,
I’m going through the document of AWR1843BOOST evaluation board (the recommended application is automotive radar) at
http://www.ti.com/lit/ug/spruim4a/spruim4a.pdf and have three elementary questions to page 11.
„This antenna design enables estimation of distance and elevation angle that enables object detection in a three-dimensional plane.“
- What type of antenna elements is used here? It seems every element has 3 pads on PCB. Why do transmitter antennas have a distance > λ/2?
- Why elevation angle? I think azimuth shall be determined.
- three-dimensional plane: A plane is always 2D, right?
I’d be thankful if anyone could help.
