ABSTRACT:
A wideband compressive receiver using only one surface acoustic wave (SAW) device in a time-multiplexed fashion. A short pulse into the SAW device generates a "downchirp" local oscillator sweep signal which, after appropriate band limiting, is mixed with the incoming signal of unknown frequency. The lower sideband is filtered out and applied to the same SAW device as an "upchirp". Timing of the resulting compressed pulse emanating from the SAW device output is related to the frequency of the unknown signal.
