To generate a radar transmit signal, a harmonic waveform x(t)=Acos(2πft) is pulsed every 0.25 ms with f = 9GHz Amplitude A is set such that the peak power is 300 kW. Duty cycle is 0.9%. Radar signals feeds circular antenna with 1 m diameter and 75% aperture efficiency.

d) What is the approximate antenna gain?
e) What is the maximum radial velocity that can be unambiguously measured?
