Patent number: 10069526Abstract: A device is provided for correlating at least one noisy analog signal which is one of a plurality of signals obtained by a plurality of receivers. The device comprises a 1-bit quantization element to which is supplied, in use, the noisy signal; a comparator configured to compare the quantized signal with a reference signal which is a consensus signal obtained by averaging data from the plurality of receivers; and an up/down counter that is configured to be incremented by a subset of the comparison signal.Type: GrantFiled: April 14, 2017Date of Patent: September 4, 2018Assignee: Phasor Solutions LimitedInventor: Richard Hammond Mayo

Patent number: 10008772Abstract: An element of a phased array antenna is provided. The element comprises a phase tracking circuit configured to multiply the in-phase component (In) of a local output signal by the quadrature phase component (Qout) of an external output signal to generate a phase control signal (535) and/or to multiply the quadrature component (Qn) of a local output signal by the in-phase component (Iout) of an external output signal to generate a phase control signal (535).Type: GrantFiled: November 19, 2013Date of Patent: June 26, 2018Assignee: Phasor Solutions LimitedInventor: Richard Mayo
