Claim Text:
1. A range monitoring system, the system comprising: a first antenna configured to be located at a first location; a second antenna configured to be located at a second location, the first antenna to be spaced from the second antenna; and a transceiver, said transceiver comprising a co-located transmitter and receiver, said transceiver coupled to said first antenna through a first communication link and said transceiver coupled to said second antenna through a second communication link; said first communication link adapted for maintaining a known or fixed time delay in the presence of relative motion of said first location relative to said second location; said first communication link adapted for maintaining a known or fixed time delay in the presence of operative relative motion of said first antenna relative to said transceiver; said transceiver configured for transmitting a transmitted wide band signal using said first antenna and receiving a received wide band signal responsive to said transmitted wide band signal using said second antenna, said transceiver configured to measure a first time difference between said transmitted wide band signal and said received wide band signal, said first time difference indicative of said range wherein the first communication link is a flexible transmission line sufficiently flexible to allow said operative relative motion of said first antenna relative to said transceiver.
