ABSTRACT:
An ultra-widebandwidth compressive receiver includes a power divider for processing a composite input signal consisting of individual input signals. The power divider provides a plurality of power divided signals to corresponding nondispersive delay lines. Each nondispersive delay line generates a unique time delay for each power divided composite signal. The unique time delay is generated in accordance with an arithmetic progression. The unique time delay has the effect of altering the phase of a corresponding individual input signal. The time delayed composite signals are provided to a frequency converter which heterodyne mixes them with local oscillator signals of frequencies which are a base frequency plus multiples of a reference signal frequency. The result is provided to a power combiner which re-combines the time delayed and frequency converted individual input signals in order to generate a group of narrow signal pulses that are separated in time according to their frequency.
