  • Patent number: 5648940
    Abstract: The signal appearing at the receiver input of a pulse code active sonar dng a return echo period, is sampled, time compressed and stored in a memory. The time compressed sample is successive read-out of memory, with each individual "read-out" hetrodyned with a discretely different doppler compensation frequency signal. The successively processed read-outs are passed through an "on line" correlation detection device to determine presence of a correctly compensated pulse code echo.

  • Patent number: 4754282
    Abstract: A data analysis system accepts time related data samples which are develo from sets of common wavefronts incident upon a plurality of sensors. The data samples are converted from analog-to-digital form and the Fourier transforms relative to the frequency components are generated. The frequency components of the Fourier transforms are in turn cross-correlated for developing matrices of all possible correlations for each frequency component and then the matrices are integrated over a determinable time period. The resultant integrated matrices are compared with signals representative of an incident plane wave power as a function of its angles of arrival at a sensor array and of its frequency, producing output signals of relative strength indicative of the direction of the origin of the data samples.

  • Patent number: 4500886
    Abstract: A data link for an automatic aircraft carrier landing system is described which an aircraft is guided to the carrier by pitch and bank information from the carrier so as to indicate to the pilot of the aircraft whether he is within a prescribed flight path for landing or whether he should be waved off for another approach. The information transmitted from the carrier is received by a microelectronic data link receiver having an internal clock which is synchronized with the incoming information to determine if that particular aircraft is being addressed and if so, what the nature of this information is so that it may be stored and presented to the pilot at a later time for appropriate action.

  • Patent number: 4291984
    Abstract: An improvement for a fiber interferometer gyro provides for greater rotation rate sensitivity. The gyro has a single mode fiber coiled about an identical area a great number of times. A single external laser sends pulses of energy which are split and passed in opposite directions through the coiled fiber and a pair of optical amplifiers inserted to amplify the energy pulses. This permits the length of the coiled fiber to be increased and, hence, provides for greater interferometer sensitivity.

  • Patent number: 4210881
    Abstract: A planar millimeter wave microstrip triplexer for separating three contigs bands of frequencies (lower, middle and upper bands). The middle band is separated by the use of a diplexer comprising two quadrature couplers connected by dual identical planar bandpass filter sections. A second diplexer comprised of two edge-coupled filter sections is connected to the isolated port of the input quadrature coupler of the first diplexer. Signal components contained in the upper and lower frequency bands appear at the respective outputs of the second diplexer.

  • Patent number: 4201987
    Abstract: A method for determining antenna near-fields from measurements on a spherical surface. Phase and intensity values are measured by scanning a probe antenna over a spherical surface. The method applies both to planar or conformal antennas. The spherical surface may be in the Fresnel or Fraunhofer regions. The field at the antenna is computed utilizing the complex conjugate of the measured field. As a result, the source antenna at the point at which the antenna radiating field is evaluated is inside the measurement surface. Far-field patterns can be computed from the near-fields reconstructed from the spherical hologram surface.

  • Patent number: 4200873
    Abstract: A low profile transmitting antenna consisting of a circular slot in a coal cavity that is folded several times. The last inner fold of the coaxial cavity is loaded with the tuning coil. The tuning coil can in the alternative be connected in series with the transmitter leeds connected to the radiating slot. Concentric cylinders alternately attached to the top and bottom of the cavity are used to form the folded coaxial cavity that provides the equivalent of a tapered transmission line. Energy to be transmitted is fed across the circular slot of the antenna or in the alternative may be fed into the last inner fold in the center of the cavity. The antenna radiates energy out with the same radiation pattern as a vertical monopole antenna.
