Abstract:
A radiofrequency pulse memory system is described. There is provided a plurality of cavity resonators each resonant at a different frequency to detect a radiofrequency (RF) pulse having a frequency equal to the resonant frequency of the detecting resonator. A plurality of RF signals are locally generated each having a frequency equal to the frequency of the detected pulses. An arrangement responds to a detected pulse to provide at the system output an RF signal having a frequency equal to the frequency of the detected pulse for a variable period of time greater than the period of time of the detected pulse.
