Not really. Even at the intended target, it's diffuse enough not to raise body temperature much. Birds could fly through without harm. Under the antenna, there'd be very little microwaves leaking through. Aim anywhere without a homing signal and you lose the coherent beam, making it much more diffuse.

iirc, Novar Conrols/Novar Electronics out of Barberton Ohio (at the time) was testing the phased arrays using bees and their hives and what ever else got in the area. Oh, yeah, and apparently some of the engineers and the boss.

(I used to work in a lab there next to some of the equipment and one day I asked my good friend about it - he had been there for decades.)
