Part Number: IWR6843AOP
According to the formula listed in the Beamsteering for Corner Radar Reference Design, the steering vector is
[0, 2*PI*d2*sin(theta)/lambda, 2*PI*d3*sin(theta)/lambda]
My understanding about the antenna pattern used in ISK-ODS is that the 3rd transmitter is on the vertical direction so that its delay phase should be PI rather than 2PI :
[0, 2*PI*d2*sin(theta)/lambda, PI*d3*sin(theta)/lambda]
Is it right? please correct me and give a formula if my understanding is wrong.
This beamsteering design is intended for use with the ISK - in which the second antenna is elevated. This is not intended to work with the ISK-ODS.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

For the beam steering to azimuth = theta and elevation = 0, the phase can be always calculated as:
Where d2 is the antenna space between TX2 and TX1.
d3 is the antenna space between TX3 and TX1.
In the case of ODS pattern, d2 = 2*lambda, and d3 = 2*lambda.
