ABSTRACT:
A multiplexed multi-channel DRFM is disclosed including at least one input and output mixer, D/A and A/D conversion means and a random access memory for receiving digital representations of the incoming RF pulse. A channel detector responsive to the frequency of the incoming pulse and an N channel switch responsive to the channel detector selectively connects one of a plurality of local oscillators to the DRFM mixers as the frequency of the incoming RF pulse changes with time.
