Source sentences:
text: By timing the pulses on an oscilloscope, the range could be determined and the direction of the antenna revealed the angular location of the targets.
text: Range is determined by measuring the time from transmission of a pulse to receiving the echo from a target.
text: The range to a target is determined by measuring the time that a radar signal takes to travel out to the target and back.
text: Range measurement and resolution are achieved in Synthetic Aperture Radar (SAR) in the same manner as most other radars: range is determined by measuring the time from transmission of a pulse to receiving the echo from a target and, in the simplest Synthetic Aperture Radar (SAR), range resolution is determined by the transmitted pulse width, i.e. narrow pulses yield fine range resolution.
text: Modern radars, especially air-to-air combat radars in military aircraft, may use PRFs in the tens-to-hundreds of kilohertz and stagger the interval between pulses to allow the correct range to be determined.
text: Pavel K. Oshchepkov on the PVO technical staff in Moscow, strongly believed that the radiolokatory (radio-location) equipment should be pulsed, potentially allowing range to be determined directly.
text: A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined.
text: This allows the bistatic range of the object to be determined.
text: Given this insight, it is quite reasonable to say that the range can be determined no more accurately than cPW/2 or equivalently
text: The minimum range, in yards, at which a target can be detected is determined using the following formula (pulse width and recovery time are expressed in microseconds or fractions of microseconds):
