    摘要: A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a synchronization check, and/or a command check of the multipath impulse radio signal.

    摘要: A system for duplex transmission and reception utilizing circular polarization wherein a pair of linear polarized orthogonal antennas is coupled to a transmitter through a hybrid coupler and a receiver is coupled to the antennas via the same hybrid coupler by using the port isolated from the transmitter. The hybrid may be a quadrature hybrid coupler or may comprise a 180 degree hybrid combined with a 90 degree phase shift network. Embodiments are shown for receiving a first reflection (opposite handed sense) circular polarized wave and alternatively, for receiving a second reflection (same handed sense) (multi-path) circular polarized wave.

    摘要: An unpolarized electro-optically Q-switched laser using a laser rod (4), a prism (1) and a Pockels cell (5) between a pair of mirrors (2, 3) wherein the prism (1) is selected to give a low-angle walk-off arranged that when a quarter wave length voltage is applied to the Pockels cell the first pass will be cancelled by an equal and opposite walk-off during the return path.
