  • Patent number: 9751562
    Abstract: A park exit assist system includes an electronic control unit. The electronic control unit is configured to detect a situation around a host vehicle parked or stopped in a parking/stopping area on a roadside. The electronic control unit is configured to calculate, on the basis of a detected result of the situation around the host vehicle, a park exit guidance path along which the host vehicle is moved out of the parking/stopping area to a traffic road and in which a steering angle becomes neutral at the time when a roadside front end of the host vehicle advances into the traffic road. The electronic control unit is configured to guide the host vehicle from the parking/stopping area toward the traffic road by at least executing steering control along the park exit guidance path.

  • Patent number: 8686326
    Abstract: In certain aspects, this invention is a “control system” that detects and minimizes (or otherwise optimizes) an angle between vehicle centerline (or other reference axis) and vehicle velocity vector—as for JDAM penetration. Preferably detection is exclusively by optical flow (which herein encompasses sonic and other imaging), without data influence by navigation. In other aspects, the invention is a “guidance system”, with optical-flow subsystem to detect an angle between the vehicle velocity vector and line of sight to a destination—either a desired or an undesired destination. Here, vehicle trajectory is adjusted in response to detected angle, for optimum angle, e.g. to either home in on a desired destination or avoid an undesired destination (or rendezvous), and follow a path that's ideal for the particular mission—preferably by controlling an autopilot or applying information from navigation.

  • Patent number: 8354952
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for radio phase retrieval. A system practicing the method gathers first data from radio waves associated with an object observed via a first aperture, gathers second data from radio waves associated with the object observed via an introduced second aperture associated with the first aperture, generates reduced noise data by incoherently subtracting the second data from the first data, and performs phase retrieval for the radio waves by modeling the reduced noise data using a single Fourier transform. The first and second apertures are at different positions, such as side by side. This approach can include determining a value Q which represents a ratio of wavelength times a focal ratio divided by pixel spacing. This information can be used to accurately measure and correct alignment errors or other optical system flaws in the apertures.

  • Patent number: 8154438
    Abstract: The present invention can find the exact location anywhere in the nautical world (latitude/longitude coordinates) by correlating or matching radar returns with maps produced by a digital nautical chart called a Chart Server, because each pixel location on the Chart Server maps can be traced back to a latitude/longitude coordinate. An obstacle avoidance module called a Chart Server provides digital nautical charts to create a map of the world. To determine the current world location of a vehicle, the invention combines the Chart Server maps with a radar return, which also appears to display prominent features such as coastlines, buoys, piers and the like. These return features from the radar are correlated or matched with features found in the Chart Server maps. The radar then reports its current location inside of its local map, which when translated to the Chart Server map, correlates to a latitude/longitude registration location.

    Abstract: A land-based smart sensor system and several system architectures for detection, tracking, and classification of people and vehicles automatically and in real time for border, property, and facility security surveillance is described. The preferred embodiment of the proposed smart sensor system is comprised of (1) a low-cost, non-coherent radar, whose function is to detect and track people, singly or in groups, and various means of transportation, which may include vehicles, animals, or aircraft, singly or in groups, and cue (2) an optical sensor such as a long-wave infrared (LWIR) sensor, whose function is to classify the identified targets and produce movie clips for operator validation and use, and (3) a supercomputer to process the collected data in real-time. The smart sensor system can be implemented in a tower-based or a mobile-based, or combination system architecture. The radar can also be operated as a stand-alone system.

  • Patent number: 8013780
    Abstract: A radar sensing system for a vehicle includes a radar sensor device, a cover panel and a control. The radar sensor device is disposed at a pocket established at an upper edge of the vehicle windshield and having a forward transmitting and receiving direction that is not through the windshield. The cover panel is disposed at the radar sensor device and is substantially sealed at the vehicle windshield at or near the pocket at the upper edge of the vehicle windshield. The cover panel has a material that is substantially transmissive to radar frequency electromagnetic radiation waves. The radar sensor device emits radar frequency electromagnetic radiation waves that transmit through the cover panel. The control is responsive to an output of the radar sensor device.

  • Patent number: 8009081
    Abstract: A moving sensor suite for imaging a scene has three Doppler radars, two moving and one fixed, a fixed video camera and a fixed GPS receiver. The Doppler radars measure the relative velocities between the radars and the scene, as well as the scene's electromagnetic reflectivity, while the video camera records the motion of the camera and the optical property of the scene. The correct registration of the Doppler radars and the camera is established by finding the intersections of the moving Doppler radar motion vectors with the image plane of the video camera. The scene features in the first frame are determined by Doppler circle intersections. The correspondences of the features in the next two frames are established by a feature matching operation.

  • Patent number: 7889113
    Abstract: An inspection system that can detect contraband items concealed on, in or beneath an individual's clothing. The system employs millimeter wave radiation to detect contraband items. The system is described in connection with a check point security system that includes temperature controlled walls to enhance imaging of contraband items. Also, a millimeter wave camera is used in conjunction with a visible light camera that forms images. To address privacy concerns of displaying images of people made with millimeter wave cameras that effectively “see through” clothes, the millimeter wave images are not displayed directly. Rather, computer processing produces indications of suspicious items from the underlying raw millimeter wave images. The indications of suspicious items are overlaid on the image formed by the visible light camera.

    Abstract: The system and method for standoff detection of human carried explosives (HCE) automatically detects HCE (112) up to a range of (200) meters and within seconds alerts an operator to HCE (112) threats. The system (100) has radar only, or both radar and video sensors, a multi-sensor processor (102), an operator console (120), handheld displays (122), and a wideband wireless communications link. The processor (102) receives radar and video feeds and automatically tracks and detects all humans (110) in the field of view. Track data continuously cues the narrow beam radar (118) to a subject of interest (110), (112) the radar (106), (108) repeatedly interrogating cued objects (110), (112), producing a multi-polarity radar range profile for each interrogation event. Range profiles and associated features are automatically fused over time until sufficient evidence is accrued to support a threat/non-threat declaration hypothesis.
