Abstract: A system for converting several analog signals to digital signals using a single analog to digital converter. Each of the analog signals is encoded, using multiplication, with a different binary code, and the encoded analog signals are summed, and converted to digital form by an analog to digital converter. Multiple digital data streams are then formed from the digital output stream produced by the analog to digital converter, by forming correlations of the digital output stream with each of the binary codes.

Abstract: A system for beamforming, in a phased array antenna. Subtraction of a sinusoidal signal from a received signal, or from a signal to be transmitted, is used to shift the phase of the received signal, or from a signal to be transmitted. A separate sinusoidal signal may be generated for each antenna array element, making it possible to shift the phase on a per-element basis, to perform beamforming.

Abstract: An electronic warfare (EW) devices and a method of providing jamming techniques are generally described. Firmware is updated by eliminating an existing jamming technique, adding a new technique and/or changing parameters of one of the techniques in the firmware. Changing the technique parameters includes adding a new parameter, deleting an existing parameter, changing the range of values for an existing parameter and changing the order of the parameters to be transmitted by an Operational Flight Program (OFP) to the firmware to generate the technique. The OFP reads a published a register mapping specifying parameters to use in generating the jamming techniques in the EW firmware, a range of the parameters and an order of the parameters. The jamming techniques are generated using parameters transmitted by the OFP to the firmware. The same OFP is used to trigger generation of jamming techniques prior to and after the updating of the firmware.

Abstract: A butterfly channelizer includes at least two stages. Each stage includes at least one dual-channel module configured to convert an input time domain signal into a second time domain signal of lower bandwidth. At least one clock is configured to generate a clock signal that drives the at least two stages. A first stage has a first number of dual-channel modules and a second stage following the first stage has a second number of dual-channel modules greater than the first number.

Abstract: Described herein are methods and systems capable of generating weighted parameter sets, which can be randomly addressed for dictating a waveform of each pulse to be generated by using a probability distribution function loader to load a memory table with waveform parameter values, wherein the values are loaded according to a weighted probability distribution function. Each value is then randomly addressed in the memory table and/or randomly selected from the memory table by a random number generator and fed into a signal generation circuit for creation of the waveform to be transmitted.

Abstract: A system and method of digital beamforming for a monobit phased array radar system includes providing a plurality of monobit analog signals received by at least one antenna to at least one field programmable gate array (FPGA). A plurality of monobit SerDes transceivers within the FPGA convert the plurality of monobit analog signals into a plurality of multibit digital signals, each of the multibit digital signals being modified according to a digital signal conditioning value to calibrate, phase align, and synchronize the digital signals. A digital beam is formed by coherently combining the plurality of digital signals within the FPGA.
