摘要： An interference cancellation system (ICS) may be used with a communication system to prevent or minimize interference from one or more sources. The ICS may receive radio RF signals comprised of one or more signals of interest (SOI) and multiple interfering signals. The ICS may use a sample of the interfering signals to cancel the interfering signals from the SOI. The multiple interfering signals may be converted into a single optical signal for cancellation. One or more optical cancellation paths may be used for interference cancellation. Each optical cancellation path may include an optical attenuator and/or an optical delay to achieve phase shifts and/or delays for interference cancellation.

摘要： An apparatus for electronic warfare signal simulation which is used in an external test system to simultaneously test a plurality of “victim” communication systems for vulnerability to jamming. The test system includes a remote radiator of a signal free of jamming effects, and a remote radiator of one or more radio frequency control signals which represent one or more predetermined jamming threats in the low and mid bands. The simulation apparatus has a pair of couplers, each adapted to be coupled between a respective one of a plurality of “victim” antennas and its associated “victim” receiver, for coupling off the control signals to a receiving circuit, a plurality of modules for generating simulated jamming signals, and a band select circuit for translating the frequency of each simulated jamming signal, setting its level to that determined for its control signal, and replicating the “victim” antenna gains, and feeding the modified simulated jamming signals together with the desired signal to the plurality of “victim” receivers.

摘要： A system for retrieving at a given station, either on the ground or in their, data from a site on the earth's surface from which ground-based communication would be impracticable, either because of configuration of terrain or of the existence of intervening natural or man-made obstacles, wherein an assembly comprising a rocket module and a surface module connected together by an umbilical connector is emplaced directly or by air drop at the site and wherein the data is acquired at the site by sensors located within the surface module and recorded by a recorder located within the rocket module. Upon command from the given station, or after a predetermined time set by an electronic clock, the rocket module is launched into near space, and, upon attainment of an altitude at which suitable line-of-sight transmission of energy can be accomplished, a transmitter in the rocket module connected to the recorder is actuated, permitting the recorded data retrieved from the surface to be transmitted from the rocket module to the aforesaid station.
