Abstract:
1. In a wideband radio system that measures a distance traveled by wideband burst signals from a transmitter that transmits said wideband burst signals, said wideband burst signals having a time spacing, a receiver, comprising: an antenna that converts said wideband burst signals impingent thereon into received signals; a delay component, said delay component outputting a delay timing signal relating to said distance; a local waveform generator responsive to said delay timing signal and configured to generate local signals, said local signals being substantially similar to said received signals and affected by said delay timing signal; a coincidence detector responsive to said received signals and to said local signals such that said received signals and said local signals synchronously arrive at said coincidence detector in accordance with said time spacing, said coincidence detector generating a product signal; and an integrator means responsive to said product signal and providing a integrated signal, wherein said integrator means is comprised of: a first integrator, responsive to said product signal output from said coincidence detector; said first integrator providing a first integrated signal; and a second integrator responsive to said first integrated signal, said second integrator providing a second integrated signal, said second integrated signal being the integral of a plurality of said first integrated signals.
