AWR1642: the antenna

Slithice
Intellectual 295 points
Part Number: AWR1642
According to your theory, the largest unambiguous field of view (FOV) of the radar is ± 90° when the distance of two separated RX antennas is lambda/2. However, there is an antenna field of view ±60°With angular resolution of approximately 15° in your technical documents for AWR1642. I want to know what the difference between two angles is？ Which angle is the true value when we measured?

    Hello,

    The FOV provided by the antenna spacing is a theoretical max FOV that can be achieved. The antenna gain would typically reduce as we move away from the center and hence the max range  would reduce as you move at an angle. Based on the antenna pattern, you look at the gain provided by the antenna at the desired angle and based on the distance of interest, object of interest (RCS) etc. you can compute upto what angle your object would be visible.

    You can use the sensing estimator  tool to help you estimate what the kind of min antenna gain you would need for your use case and then then estimate the angle at which that is achievable from the antenna pattern. 

    regards,
