Question 1 of 10

1. Which of the following is false with respect to PESA?

All elements combine to a single receiver. Each element steers the beam through phase shifters

PESA can only have one main beam and one transmit power source

Because it uses a, multiple frequencies, it is less susceptible to enemy jammers

PESA is more technically simple
