Abstract: Embodiments are directed to operating an analog signal processing circuit to emulate a Rotman lens. The analog signal processing circuit applies a plurality of time delays to a plurality of signals associated with a plurality of beam ports. The analog signal processing circuit forms a plurality of output beams for transmission by a plurality of array ports included in an array based on the time delayed signals by summing the time delayed signals. The time delays are based on a direction of transmission of the output beams.

Abstract: An electronic analog memory system includes at least one analog programmable delay module configured to receive an input radio frequency pulse. The analog programmable delay module generates a time delayed output signal in response to applying at least one time delay to the input radio frequency pulse. A switching module is configured to selectively deliver the time delayed output signal to an output of the electronic analog memory system. The electronic analog memory system further includes an activity detector module configured to determine the amplitude of the input radio frequency pulse. The activity detector module also controls the switching module to deliver the time delayed output signal to the output in response to the at least one amplitude exceeding an amplitude threshold.

Abstract: An RF module including transmitting, receiving, and processing elements, capable of operating in a standalone mode or as part of an array of similar or identical modules. The RF module includes a radiator (205), transmit-receive circuitry (165), a digital receiver-exciter (160), a processor (100), and a data interface (150). The processor is configured to exchange in-phase and quadrature data with other processors in an array, so that, when configured as an array, digital transmit beam forming and receive beam forming are possible.

Abstract: Method and apparatus for leakage signal cancellation in a simultaneous transmit and receive RF system includes: generating a digital transmit signal for transmission from the system; receiving a receive signal produced by reflection of the transmit signal from an object or generated by a second RF system; adaptively filtering the transmit signal by an adaptive finite input response (FIR) filter; calculating filter coefficients for the adaptive FIR filter in real-time at a different sampling rate; adaptively inputting the calculated filter coefficients to the adaptive FIR filter to generate a cancellation signal in real-time; and applying the cancellation signal to the receive signal to cancel leakage in the receive signal to generate an optimum receive signal.

Abstract: Method and apparatus for a phased array system including a plurality of unmanned aerial vehicles (UAVs) configured to fly in an array formation having an array lattice spacing. The UAVs can include a puck having a phased array element and a signal processing module configured to receive and process a signal to achieve for the array lattice spacing a spacing that is less than a wavelength of operation of the phased array elements.

Abstract: System and method for signal modulation. In one embodiment, a circuit includes a channel for carrying an analog RF signal, a phase offset circuit on the channel, and configured to receive a phase code for modifying the analog RF signal to produce a modified RF signal, and a feedforward cancellation path coupled in parallel to the phase offset circuit for canceling a portion of the modified analog signal.
