Abstract

A radio frequency pulse multiplier for producing coherent multiples of radio frequency (rf) pulses comprising an input terminal for receiving rf pulses, a signal divider for providing a plurality of pulses in response to an input pulse, the output of the signal divider coupled to a plurality of signal paths, each respective path comprising a time delay element providing a selectable delay to a respective pulse, a signal combiner for combining the plurality of pulses on a single output, and an output terminal. The output of the multiplier comprises pulses delayed by amounts equal to the preselected delays in the respective signal paths of the multiplier. The multiplier may comprise signal conditioning elements for conditioning the rf pulses within the multiplier. In another embodiment of the invention, a plurality of the pulse multiplier may be arranged in a cascade, whereby the cascade produces a number of pulses that is the arithmetic product of the number of pulses produced in the respective stages of the cascade. The multiplier may further embody a notch filter for substantially rejecting an rf pulse train of frequency f by selecting the time delay equal to the period 1/f of the input pulse frequency.
