This calculator helps determine the pulse repetition frequency (PRF) and pulse repetition time (PRT) in radar systems. It is used to relate the maximum unambiguous range to the transmission frequency of radar pulses, thereby helping to design and analyze the performance of a radar system.
Formulas
PRF (Hz) = c / (2 × R max )
PRT (s) = 1 / PRF
where c = 3 × 10 8 m/s
Explanation of formulas
The pulse repetition frequency (PRF) represents the number of radar pulses transmitted per second. It depends on the maximum unambiguous range (R max ), which is the greatest distance at which a target can be detected without distance ambiguity. Pulse repetition time (PRT) is simply the reciprocal of PRF, indicating the time between two successive pulses.
Uses of the calculator
- Design and optimization of pulse radar systems.
- Evaluation of unambiguous range and radar scan rate.
- Training and research in radar engineering and detection systems.
- Performance analysis in military and civil applications.
