Separate thread created on request.
I refer to the document tidueh0.pdf which is the document accompanying this design.
Q1. In page 13 , where you have explained NURA antenna design resulting in a 4x3 array being generated. In the diagram it is suggested that 2 Rx antennas are in the same horizontal plane, looking at the PCB gerbers this appears to be visually correct. However the 2 Tx antenna's are not visually in a horizontal plane compared to the 2 Rx antennas. Can you please explain whether the additional Tx antenna and the Rx antenna's have to be in the same horizontal plane to improve the azimuth estimation capacity by a factor of 2? (swra554a.pdf MIMO radar document suggests so in page 5)
