Abstract :
A 0.5 ms delay line with a time-bandwidth product of > 105 is demonstrated by recirculating a 2 ns pulse around a 20.4 km single-mode fibre five times. Analogue signal regeneration is employed after each recirculation. System dynamic range, signal/noise ratio and cancellation ratio for a noncoherent moving target indicator radar application are given.
