1.	How is the radar beam moved in the ESA?(a) Phase shift(b) Mechanical gimbal(c) Mechanical servos(d) Hydraulics
Answer» The correct answer is (a) Phase shift Explanation: In ESA, the antenna’s beam is moved electronically by setting the phase angles of phase shifters located at each radiating element to provide a linear phase taper across the array surface.
