摘要: A proximity fuze (proximity fuse) comprising an ultra wideband (UWB) radar transmitter, a UWB radar receiver, an antenna, a timing system, and a signal processor. One embodiment includes an antenna with an annular conical radiation pattern. In another embodiment, a trigger delay is produced that is related to target detection range. In a further embodiment, multiple range shells are utilized to further discriminate target characteristics including velocity. A method is disclosed that utilizes target range, velocity, signal amplitude, and radar signal phase to identify the target and trigger the detonation. A proximity fuze system having a long storage life is disclosed comprising a proximity fuze element powered by a turbine generator and internal gas source.

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: A bi-phase modulator for Ultra Wideband (UWB) waveforms uses a symmetrical transformation device and a selector device to produce bi-phase modulated UWB waveforms in response to an information signal. The symmetrical transformation device receives an input UWB waveform and produces equal but opposite polarity output waveforms. The selector device determines whether an inverted or non-inverted UWB waveform is output in response to the information signal.
