The time at which the reflected pulse arrives at the needle point corresponds to the doubled time of the pulse passage over the cable and amounts to ≈13 ns.
WebRemote sensing systems which measure energy that is naturally available are called passive sensors. Passive sensors can only be used to detect energy when the naturally occurring energy is available. For all reflected energy, this can only take place during the time when the sun is illuminating the Earth. There is no reflected energy available ...
