Assuming sufficient transmission power, the maximum range of a ground radar with a pulse repetition frequency of 450 pulses per second is: (Given: velocity of light is 300 000 km/second)

Maximum Theoretical Range = c / 2 x Pulse Repetition Frequency

= 300,000 / 2 x 450

= 300,000 / 900

= 333 km

Note that the speed of light has been given in Kilometres per second, therefore the calculated answer will be given in kilometres. Wherever possible use the speed of light that corresponds with the given answers.
