Pulse repetition frequency

The maximum range from which a transmitted radar, lidar, or sodar pulse can be reflected and received before the next pulse is transmitted. This range, rmax, is given by r max = cT/2 , where T is the interpulse period and c is the speed of light (or speed of sound in the case of sodar).25 Nis 2012

Therefore, the maximum range of Radar for given specifications is 158KM .

Use Eqn (2-3) The maximum unambiguous range is 1/2 the distance that can be travelled by the radar energy during the time of one sweep from 400 to 800 MHz. … Radar Principles and Systems. frequency, f5600 MHzpulse repetition time, PRT_____peak power_____average power_____duty cycle8.3 x 10-4Radar Principles and Systems man.fas.org › dod-101 › navy › docs › workbook › WBch02

The unambiguous range of a radar is the maximum range at which a target can be located so as to guarantee that the reflected signal/pulse from that target corresponds to the most recent transmitted pulse . It is an important factor for radar.14 May 2020
