A radar using parabolic reflector antenna has the following characteristics

Peak transmitted power = 800KW

Wavelength of the transmitted wave = 2.5cm

Noise bandwidth = 2.5MHz

Radar cross section of the target = 25m2

Minimum detectable signal power = 8 Χ 10-13 W. Assume standard ambient temperature is 170C. If the above radar has a maximum range of 118.45KM,

determine

Noise figure of the radar receiver in db

A certain radar, operating at 3 GHz, with an antenna of gain of 40 dB (assumed the same for both transmission and reception) and a peak power of 1MW, can reliably detect a target if the peak power in the returned signal is at least 5 times the system noise power. If the noise power is 10-12 W, estimate the smallest radar cross section the system can detect at 40 km.
