Patent number: 5731783Abstract: This invention relates to a method and apparatus by which a coarse estimate of radar signal polarisation can be obtained. An array comprises at least three differently directed detectors. The polarisation is estimated by measuring an amplitude relationship, such as a ratio of amplitudes, for two adjacent detectors and for two non-adjacent detectors. This provides sufficient information to obtain a coarse estimate of the polarisation state, obtainable by using the value of the amplitude relationship for the two adjacent detectors together with a look-up table to estimate values of the amplitude relationship for the two non-adjacent detectors for different polarisation states, and then comparing the measured and estimated values for this amplitude relationship.Type: GrantFiled: January 23, 1996Date of Patent: March 24, 1998Assignee: Racal Radar Defence Systems LimitedInventor: Stephen Paul Martin Graham

Patent number: 5502652Abstract: Methods and apparatae for metering energy consumption in a mass transfer heat delivery system using acoustic signals. A first type of method uses the phase difference between two simultaneously generated acoustic signals to determine the flow rate of liquid through a station of the heat delivery system. A first transducer and second transducers are used to transmit the first and second acoustic signals, respectively, through the liquid in response to an applied drive signal. The drive signal is removed from the first and second transducers such that the first and second transducers may be used to detect the arrival of the second and first acoustic signals, respectively. A phase detector measures the phase difference between the two acoustic signals as detected by the first and second transducers. A second type of method uses time lag analysis. A first transducer is used to transmit an acoustic signal through the liquid towards a second transducer in response to an applied drive signal.Type: GrantFiled: August 24, 1994Date of Patent: March 26, 1996Inventors: Austin C. Hoggatt, Martin Graham, David D. Cudaback, Melvin P. Klein, John W. Otvos, Paul L. Richards
