  • Publication number: 20200379102
    Abstract: Systems and methods are provided for recognizing a human being behind a barrier using a radar image. A millimeter band radar assembly captures radar returns from a region of interest, at least a portion of which is separated from the millimeter band radar assembly by the barrier. A system control processes the radar returns to provide at least one radar image showing the amplitude of the radar return in each of a plurality of locations within the region of interest. The system control includes a sensitivity tuning component that adjusts a noise floor for the processed sensor data to provide an image of the at least one radar image tuned to maximize the visibility of the human being. A display provides the radar image to a user.

  • Patent number: 9939525
    Abstract: Systems and methods are provided for imaging a region of interest in an obscured environment. A millimeter band radar assembly is configured to capture a radar image of the region of interest. A data source provides a representation of at least a portion of the region of interest. A data fusion module is configured to combine the radar image and the representation of the region of interest to provide an enhanced representation of the region of interest.

  • Patent number: 6054947
    Abstract: A radar system for a helicopter having a mast and a plurality of blades coupled to the mast by shaft portions of the blades includes a transmitter and a receiver respectively transmitting and receiving a pulsed radar beam through a feed horn, a generator for generating the radar beam energy for transmission by the transmitter, a processor, a display, and a passive reflectarray deposited on the underside of at least one blade of the helicopter. The reflectarray is a preferably flat array of passive microstrip elements which can impart a phase to the radar beam. A typical microstrip element is a patch whose dimensions may be controlled, and the size of which determines the phase for the location within the array of that element. The reflectarray is provided with a pattern which is designed to scatter the radar beam in a desired shape and direction to produce uniform mapping of the terrain over which the helicopter travels.

  • Patent number: 4797683
    Abstract: Dual radome arrangement (15) comprising inner and outer layers (14,16) respectively transmissive to both modes of radiation operable in a detection system (11), and only one of the modes of radiation, and the outer layer (16) being selectively removable.

  • Patent number: 4794398
    Abstract: In a multimode or multispectral electromagnetic detection system (11), a pair of rotatable scanning prisms (13' and 13"), each of said prisms comprising at least a pair of cooperative subprisms (13'a, 13'b, 13"a and 13"b), and the cooperative materials of the subprism being selected so as to ensure that electromagnetic radiation passing through the pair of rotatable prisms is equally deviated in a transverse direction.

  • Patent number: 4791427
    Abstract: A multimode, multispectral antenna system (14) for detecting radiation from selected target regions in each of at least a pair of selected spectrum bandwidths through collimating lens (35), and rotatable, cooperative prisms (21) effective for collimating and scanning beams of radiation controllably with respect to said target regions.

  • Patent number: 4742358
    Abstract: A method of constructing rotatable scanning prisms (13' and 13") for a multimode detection system (13), each including first and second subprisms (respectively 13'a, 13'b and 13"a, 13"b); the method including the steps of chosing an apex angle for one of said subprisms, determining therefrom apex angles at first and second wavelengths for each of said subprisms, and evaluating whether the differences of apex angles at said several wavelengths are acceptably small.

  • Patent number: 4490719
    Abstract: A reference grid for a map matching missile guidance system is generated from a vertically polarized radar map and a horizontally polarized radar map, both of which represent radar returns from a preselected ground area. In generating this reference grid, illuminating radar pulses are alternately fed to a horizontal aperture and vertical aperture of a mapping radar. Horizontal radar returns and vertical radar returns are processed in separate channels to form a radar map of the ground area containing the target to which the missile is to be directed. A pixel-by-pixel comparison of the data in each map is performed to create a polarization diverse map which is essentially those returns from man-made objects. This map is then used by the missile guidance system as a reference grid for a final fix by which the missile obtains its final course orientation enroute to the target.
