• Pulse compression — is a signal processing technique mainly used in radar, sonar and echography to augment the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with… …   Wikipedia

• Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… …   Wikipedia

• pulse repetition frequency — In radar, the number of pulses that occur each second. Also called the pulse recurrence rate, or PRR. It should not be confused with the transmission frequency, which is determined by the rate at which cycles are repeated within the transmitted… …   Aviation dictionary
