摘要： An optical feed network (OFN) for an RF phased antenna array includes a single free-space optical beamformer that supports all of the RF electrical feed signals for the RF phased antenna array to steer an RF beam. The free-space optical beamformer can more easily scale to accommodate larger array sizes than either the discrete fiber channel or PIC implementations. Furthermore, certain embodiments of the optical beamformer avoid the complexity of having to compute FFTs for each channel to steer the beam, instead relying on the inherent function of an imaging lens to perform the FFT, which in turn facilitates rapid steering.

摘要： A sensor system and method of reducing plasma-induced communication inhibition for a main antenna includes using auxiliary antennas for detecting a density of plasma that affects operation of the main antenna, and re-orienting an electromagnetic field around the main antenna in response to the density detected to reduce effect of the plasma on the main antenna. The auxiliary antennas are also operable for data link communication and switchable such if the density of the plasma inhibits receipt or sending of signals by one of the auxiliary antennas, another one of the auxiliary antennas may be used for data link communication.

摘要： A system includes one or more radio frequency (RF) emitters (108a-108b) configured to transmit RF energy (204, 304) into a specified area (102) in order to inactivate one or more specified microorganisms (106) in the specified area. The system also includes a control system (116) configured to control the one or more RF emitters in order to adjust the RF energy transmitted by the one or more RF emitters. The control system is configured to obtain information identifying different types of microorganisms that are or might be present in the specified area over time and to adjust the RF energy transmitted by the one or more RF emitters in order to target the different types of microorganisms for inactivation over time.

摘要： Embodiments of a spread-carrier self-detecting code (SCSDC) receiver with summed-delay processing (SDP) and method are generally described herein. In some embodiments, the SCSDC-SDP receiver is arranged to generate a chip-matched filter output from a received spread-spectrum signal and perform SDP on the chip-matched filter output with a plurality of delay-processing chains. The SDP may include multiplying a conjugated and delayed chip-matched filter output with the chip-matched filter output and applying a code-matched filter that is matched to a delay-multiplied code. The outputs from the code-matched filters of each delay-processing chain may be coherently combined to provide an output having correlation peaks for use generating frequency error and timing information.

摘要： A transmitter interleaves a first pseudo-noise sequence with a second pseudo-noise sequence to provide a third pseudo-noise sequence which is transmitted and received by a receiver. An XOR of the two sequences produces a third, known-valid pseudo-noise sequence. The receiver further correlates the third pseudo-noise sequence to provide a measure of a frequency of the transmitted signal. The receiver further downconverts and filters the received signal to provide a filtered complex signal. A complex multiplier generates a complex multiplication of the filtered complex signal with a delayed version of the filtered complex signal to provide a product. The delayed version of the filtered signal is delayed by a chip period. A correlator correlates the product to provide the measure of frequency. The first sequence or the second sequence is a reference signal embedded within the information-bearing signal to aid the receiver in detection.
