A coherent frequency-hopped-waveform synthesiser, based on the detection of contradirected chirp signals within a surface-acoustic-wave tapped delay line, is reported. Attractive features are programmable bandwidth and hop duration through control of external chirps, plus the capability to synthesise many simultaneous coherent outputs.
