Abstract :
Various microwave ranging systems suitable for close-range measurement applications have been proposed. A common problem with existing designs however, is the large bandwidth required to obtain good accuracy. A new measurement approach based on determining the delay experienced by a modulating signal used to frequency modulate (FM) the microwave carrier is described. Tests show that by using high speed digital signal processing techniques, a high accuracy system which uses a fraction of the bandwidth of existing implementations is feasible
