function PRI=pri(PRF)% PRI Pulse repetition Interval (pulsed radar)% %   PRI = pri(PRF)% %   PRF = pulse repetition frequency [Hz]%   PRI = pulse repetition interval [s]% %   AIM: To convert from pulse repetition frequency (PRF) to pulse %   repetition interval (PRI).% %   TECHNICAL BACKGROUND: A pulsed radar transmitts a pulse of width tau %   every T seconds. The frequency of the transmitted pulses is then known%   as the pulse repetition frequency and can be calculated by PRF=1/T. The%   pulse repetition interval is PRI=T. PRF is more commonly used in the %   radar domain while PRI is used in the EW domain. % %   REFERENCES: "Radar Fundamentals", Ian Faulconbridge, Argos Press, 2002% %   See also PRFPRI=1/PRF;
