A pulse Doppler radar has the following specifications : Operating frequency: fo = 4 GHz ; Number of range gates required to cover the entire Inter-Pulse-Period T: Ng 500; Maximum unambiguous radial velocity: VMAX = 250 Km/hour. At t=0 second, four (4) targets are located respectively at radial distances: R₁ = 30 Km; ● R2 82.50 Km; = 1) The 1st period (0 ≤t<T). Which range gates indicate the presence of echo signals during: R3 = 82.55 Km; and R4 125 Km. = = 2) The 2nd period (T≤t <2T). 3) The 3rd period (2T < t <3T). Compute the apparent radial velocity of a target if its actual Doppler shift is : a) fDac 1.5 KHz. b) fDac = 2 KHz c) fDac = 2.5 KHz What is the minimum pulse repetition frequency PRF min required to measure a maximum velocity of 300 Km/hour without ambiguity? - What should be the resulting maximum unambiguous range?
