Consider a radar with a prf of 5 khz. what is the maximum unambiguous range, rua, of this radar, in km? if a target is located at a range of 50 miles, how many pulses will the radar have transmitted before the first echo from the target arrives? what will be the apparent range of the target in kilometers? (the apparent range is the range corresponding to the time delay from the most recent pulse transmission time to the arrival of the target echo from a previous pulse once steady state is achieved.)
Answers: 3
(Pulse repetition frequency) 
(Pulse repeition time)
Pulse Width.
![RA = R MOD [\frac{C*PRI}{2}]](/tpl/images/0355/2721/50fd1.png)
![RA = 80.45 MOD [(\frac{3x108x2x10^{-4}}{2}) *10^{-3}]\\ RA = 80.45 MOD 30\\ RA = 20.45 Km](/tpl/images/0355/2721/29d3a.png)
