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...
