  • Patent number: 6655254
    Abstract: A lightweight multiple missile launch assembly (10) adapted to carry newer heavier Maverick missiles (AGM-65D, E, F, G or K). The invention is illustrated with a BRU-33, 55 or 57 bomb rack (12) adapted to carry two LAU-117 missile launchers (24, 26). The missile launchers (24, 26) are secured to the bomb rack (12) with a suspension unit (20, 22) of unique and novel design. The suspension units (20, 22) allow for releasable engagement of the missile launchers (24, 26). This allows for different missile packages to be deployed in the field.

  • Patent number: 6653972
    Abstract: A system and method (32) for measuring line-of-sight angular rates for all-weather precision guidance of distributed projectiles (16) and a guidance system (10) based thereon. In accordance with the novel method (32) for measuring line-of-sight angular rates, first the range rates of the target (14) relative to at least two projectiles (16) is determined, as well as the position and velocity of each projectile (16). Then, the line-of-sight angular rate of the target (14) relative to at least one projectile (16) is computed from the range rates, positions, and velocities. In the illustrative embodiment, the range rate of the target (14) relative to a projectile (16) is determined based on a monostatic target Doppler measurement, a monostatic projectile Doppler measurement, a bistatic Doppler measurement of the target (14) by the projectile (16), and the carrier frequency of a data link (26) between the projectile and the shipboard system.

  • Patent number: 6650272
    Abstract: A method for exciting an antenna with a waveform having a burst width and pulse width scaled proportionately with a selected range scale and a temporal filter to address any ambiguities in range resulting from the transmission of a signal in accordance with the novel waveform. The inventive filtering method includes the step of scanning a beam including a plurality of pulses of electromagnetic energy. The step of scanning the beam includes the step of outputting a beam excited by a waveform having a burst width and pulse width scaled proportionately with a selected range scale. Reflections of these pulses are received as return signals. The returns are processed to extract range in range rate measurements. The range and range rate measurements are compressed to form a plurality of range bins. The pulses are selectively weighted to reduce sidelobes resulting from a subsequent Fast Fourier transform (FFT) operation.

  • Patent number: 6650274
    Abstract: An imaging system and method. The invention provides an intra-pulse repetition interval (PRI) agile beam technique for enhanced resolution that can be used at aspect angles near the velocity vector of a host vehicle. It is particularly useful at small scan angles where beam sharpening array times become large. At these scan angles, the bandwidth of the clutter is narrower than at higher scan angles and allows large PRIs without degradation from Doppler ambiguities. In accordance with the present teachings, sequential illumination is performed within a PRI to multiple beam locations using an agile beam. The interleaving of beams reduces map formation times compared to conventional techniques using sequential arrays. The inventive system is adapted for use with an electronically scanned (e.g., synthetic aperture array radar) antenna.

  • Patent number: 6646602
    Abstract: A system for locating the position of an emitter emitting a signal having time domain features is described. At least two platforms are used. Both have a receiver for detecting the emitter signal, an FFT channelizer to act as a bandpass filter for extracting the time domain features from the emitter signal, and a thresholder for thresholding the time domain signal. An FFT transform and a correlator using templates further extract frequency domain markers identifying the emitter. The frequency domain markers identifying the emitter are transmitted between platforms using a wireless link increasing the probability of detection of the emitter at all platforms.

  • Patent number: 6643000
    Abstract: An efficient system (10) for measuring target characteristics via a torsion mode beam of electromagnetic energy. The system (10) includes a first mechanism (34, 38, 40, 42, 16) for transmitting the torsion mode beam toward a target (12). A second mechanism (16, 18, 20) receives the resulting target return beam and provides a first signal in response thereto. A third mechanism (26, 28) employs the first signal to determine rotational characteristics of the target (12). In a specific embodiment, the system (10) further includes a fourth mechanism (20, 26) that reduces or eliminates noise in the return beam based on common mode noise rejection. A fifth mechanism (32) identifies the type of the target based on the target rotational characteristics via comparison to predetermined target rotational signatures (36).

  • Patent number: 6642496
    Abstract: In a first aspect of these teachings there is provided a radiation sensor that includes sensor optics having an entrance aperture and a two dimensional array of unit cells (10) spaced away from the aperture. Each unit cell includes a radiation detector (D1) having an output coupled to an input of a gain element, and each gain element is constructed so as to have at least one component with a value selected to set the gain of the gain element to a value that is a function of the unit cell's location along an x-axis and along a y-axis within the two dimensional array. In this manner a compensation is made for a variation of scene illumination across the two dimensional array, where the variation in scene illumination results from a relative intensity of the energy impinging on a unit area of the two dimensional array that varies, for example, by the fourth power of cosine &thgr;, where &thgr; is an angle referenced to an optical axis of the radiation sensor.
