Radar systems
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...

Military radar and missile detection systems are designed to warn a country of enemy attacks. A reliability question deals with the ability of the detection system to identify an attack and issue the warning. Assume that a particular detection system has a 0.90 probability of detecting a missile attack. Answer the following questions using the binomial probability distribution: what is the probability that one detection system will detect an attack? If two detection systems are installed in the same area...
