Which of the following is false with respect to PESA?(a) PESA can only have one main beam and one transmit power source(b) All elements combine to a single receiver. Each element steers the beam through phase shifters(c) Because it uses a, multiple frequencies, it is less susceptible to enemy jammers(d) PESA is more technically simple |

Answer» The correct option is (c) Because it uses a, multiple frequencies, it is less susceptible to enemy jammers To explain I would say: In a PESA only one transmitter drives the whole antenna and hence only one frequency can be achieved at a time. This allows it to be more susceptible to jammers. |
