A SSR has the following specifications: The transmitter gain (Gt ) = 27 dB. Antenna half-power beam width (θB) = 2.45o ERP (effective radiated power) = Pt Gt = 52.5 dB R = 256 nmi The propagation loss (LP) = -2 dB The antenna loss (La) = - 3.5 dB Pr (min) = -101 dB Would you expect an aircraft transponder to receive an adequate signal at that maximum range? Consider the SSR with specification given and interrogation pulses width of 0.5μs. If the aircraft is at the maximum range, how many times the interrogation will be done before receiving the first echo? Let the time spacing between two successive interrogations = 45 μ

Question

1- A SSR has the following specifications: The transmitter gain (Gt ) = 27 dB. Antenna half-power beam width (θB) = 2.45o ERP (effective radiated power) = Pt Gt = 52.5 dB R = 256 nmi The propagation loss (LP) = -2 dB The antenna loss (La) = - 3.5 dB Pr (min) = -101 dB Would you expect an aircraft transponder to receive an adequate signal at that maximum range?
Consider the SSR with specification given and interrogation pulses width of 0.5μs. If the aircraft is at the maximum range, how many times the interrogation will be done before receiving the first echo? Let the time spacing between two successive interrogations = 45 μ
