Consider a radar with the following specifications: f = 1250MHz, maximum radar range of 220 nautical miles, for target with radar cross section σ = 1m ^ 2 with radar antenna dimensions 12 × 4m Antenna aperture efficiency ε_a = 0.55, minimum detectable signal of a pulse S_npn = 10 ^ (- 13) W and pulse width τ = 1.5μs. Calculate the following values: A) Effective A_em aperture level and G gain in terms of dB radar antenna. B) Transmitter...

2. A search radar operates at 5 GHz by sending 3 MW pulses of 20 uus pulse duration. The gain of the radar antenna is 28 dB and the equivalent system noise temperature is 1400°K. The system loss is 1 dB. The radar cross section of a typical airplane viewed from the front is 30 mp. If the minimum signal-to-noise ratio (SNR) needed for detection is 20 dB, what is the maximum detectable range of the search radar?

21) The US Air Force is planning to attack an enemy facility using B-2 stealth bombers. Human intelligence suggests the enemy early warning radar has the following parameters: 5.6 GHz carrier signal, 1.5 MW peak power, 45 dB antenna gain, 290 K noise-effective temperature, and a 0.2 microsecond pulse length. The minimum SNR threshold for target detection is estimated to be 20 dB and the radar cross section for the B 2 is 0.1 m2. Find the range at which...

2. A pulsed airborne radar operating at 12GHz has a peak power of 1 kW and uses an antenna with directivity of 2100. Total monostatic path loss is 1.8. The radar views a surface at normal range of 3 km and grazing angle of t/2. The available received clutter power (Sre) is 1.1x10-11 What is the effective surface scattering area of σ,-2.5x10-4 for the surface? (10pts) a) b) If the radar and target orientation are changed such that the grazing...
