PROBLEM 2 a) What is the peak power of a radar whose average transmitter power is 200 W, pulse width of 1 μs, and a pulse repetition frequency of 1000 Hz? b) What is the range (nmi) of this ground-based air surveillance radar if it has todettect a targer with a radar coss section of 2 m2 when it operates at a frequency of2.9 GHz (S band), with a rectangular-shaped antenna that is 5 m wide , 2.7m high, antenna aperture efficiency ρa= 0.6, and minimum detectable signal equal to Smin =10-12 W (based on Pt in the radar equation being the peak power)? c) Sketch the receiver echo signal power as a function of range from 10 to 80 nmi.
