Hello William,

This question has been answered by our experts in the past. Please look for some similar threads on the E2E forum.

Here is the link to one of those threads : (+) AWR1243: Which sensor for long range detection - Sensors forum - Sensors - TI E2E support forums

Hi.. in the given link. they have asked me to read the user guide of AWR1443 EVM. However the Field of view data is not present in the document. What is the field of view of each individual AWR1243 Sensor?

Hi,

First, it is important to understand what the Field of View is.

The FOV is the beam width at a certain db drop that can be determined from the radiation pattern

It is a property of the antenna and the sensor. The AWR1243BOOST is an evaluation board that has an AWR1243 sensor and PCB antenna.

The radiation patterns are provided in the EVM user guide in Figure 11 and Figure 12

www.ti.com

So, for example, at 78 GHz, based on 6-dB drop in the gain as compared to bore sight, the horizontal 6dB-beamwidth is approximately ±45 degrees (see Figure 11), and elevation 6dB-beamwidth is approximately ±20 degrees

Thank you

Cesar
