  • Patent number: 7376247
    Abstract: A target detection system using an EHF radar and the image processing is disclosed, in which the processing time is shortened by mutually complementing the disadvantages of the EHF radar and the image processing thereby to improve the reliability. The system comprises a radar, an image acquisition unit and an image processing ECU. The microcomputer of the ECU specifies an image recognition area based on the power output from the radar, and carries out the image processing only within the specified recognition area for the image obtained from the image acquisition unit. By performing the image processing only for the area where a target is detected by the radar, the time required for image processing is shortened on the one hand and the erroneous detection of letters on the road surface or the like is eliminated.

  • Patent number: 7339516
    Abstract: A method to present easily understood images that represent targets that are detected through walls or other opaque barriers is disclosed. This method is particularly well suited for sense-through-the-wall radar systems. One of the main challenges of evolving STTW systems is that the practitioners of the technology are generally presented with complicated images to represent the gain adjusted amplitude of signals that are detected by the radar. Interpretation of images from prior art, which can be in the form of the radar speckle, target blob, wiggle plot, and horizontal amplitude intensity displays, shown in FIGS. 1 through 3, requires high levels of skill, focus, and time. Naturally, the foregoing places military and law-enforcement customers of the technology at considerable risk during hostile missions. This invention discloses a method that converts a typical radar signal into an image that is easily understood by a practitioner of STTW technology.

    Abstract: A device including a radar and a camera for detecting an object located in front of an automobile is mounted on the automobile. The radar detects a distance from the automobile to the front object, and the camera takes an image of the object. When the object such as a preceding vehicle moves out of a region detectable by the radar while remaining in a region covered by the camera, a present distance to the object is calculated based on the distance previously detected by the radar and memorized in a memory and a present object image taken by the camera. More particularly, the present distance is calculated by multiplying the memorized distance by a ratio of an object size in the memorized image to an object size in the present image.

  • Patent number: 6967612
    Abstract: The system and method for standoff detection of human carried explosives (HCE) is a portable system that automatically detects HCE up to a range of 200 meters and within seconds alerts an operator to HCE threats. The system has radar only, or both radar and video sensors, a multi-sensor processor, an operator console, handheld displays, and a wideband wireless communications link. The processor receives radar and video feeds and automatically tracks and detects all humans in the field of view. Track data continuously cues the narrow beam radar to a subject of interest, the radar repeatedly interrogating cued objects, 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. Once a determination is made, the system alerts operators through a handheld display and mitigates the threat if desired.

    Abstract: Existing positioning technologies used in conjunction with Ground Penetrating Radar (GPR) are generally too time-consuming or insufficiently accurate for high resolution, high frequency, 3-d structural investigations. The invention provides an optical positioning system for use in GPR surveys that uses a camera mounted on the GPR antenna that takes video of the surface beneath it and calculates the relative motion of the antenna based on the differences between successive frames of video. Positioning accuracy to within several millimeters is provided. The procedure is orders of magnitude faster than surveying a grid of data points or laying out parallel lines and surveying each line with an odometer wheel. The system and method of positioning is suitable for mapping the subsurface of structures such as building columns or floors using GPR. Time domain synthetic aperture radar algorithms can be used to reconstruct an image of the subsurface using this position data.

  • Publication number: 20030011509
    Abstract: A method for detecting a target located above a road by using a camera and a radar system, wherein when it is determined that the target captured by the camera is the same target that has been captured by the radar, and when it is determined from an image captured by the camera that the target is at a height higher than road level, the method determines that the target is a stationary object located above the road. Further, when it is determined that the distance to the target captured by the camera or the radar is decreasing, and that the reception level from the target captured by the radar is also decreasing, the method determines that the target is a stationary object located above the road.

  • Patent number: 6452535
    Abstract: A pre-crash sensing system is provided for sensing an impact of a target vehicle (46) with a host vehicle (12). The target vehicle (46) has side transponders that generate side identification signals. The host vehicle (12) has a remote object sensor (20) that generates an object distance signal in response to the target vehicle. A countermeasure system (42) resides in the host vehicle (12). A controller (14) in the host vehicle is coupled to the remote object sensor (20) and the countermeasure system (42). The controller (14) activates the countermeasure in response to the object distance signal and side identification signal.

  • Patent number: 6424290
    Abstract: The tracking of moving vehicles over long distances without emitting illumination signals is accomplished with a narrowband passive differential tracking system. Instead of Providing especially designed radar transmitters in a bistatic radar system, illuminators of opportunity (which may include UHF and VHF television station) are selected by their geographic locations so that they are in proximity to a moving target. The Doppler-shifted target reflected signals from the illuminators of opportunity are converted into digital data and combined with the independently derived initial target location and used to update the target's position and velocity by correlating the Doppler-shift with geographic coordinates. The correlation can be accomplished with a tracking algorithm which was designed for use in data processing of the signal processing system of the narrowband passive position tracking system.

  • Publication number: 20020060640
    Abstract: A Doppler radar transceiver in a traffic monitoring system includes a pyramidal horn antenna having a rectangular aperture and a dielectric lens mounted at the rectangular aperture. Preferably the pyramidal horn antenna is corrugated and the rectangular aperture has a breadth at least twice its width in order to provide a fan-shaped radar beam most effective for detecting moving vehicles in a stream of traffic. To reduce standing waves in the horn antenna that would otherwise cause nulls that would intermittently interfere with detection of a Doppler signal, the dielectric lens has impedance matching means for matching impedance of the dielectric lens to impedance of free space to reduce standing waves in said horn antenna. Suitable impedance matching means include a quarter-wave transformer or a tapered transformer structure at the interfaces between the dielectric body of the lens and the free-space region inside the horn and outside of the horn.
