  • Patent number: 9954955
    Abstract: A shared radar and communication system for a vehicle includes capabilities for radar detection and communication with vehicles equipped with similar systems. The radar system is equipped with pluralities of transmit antennas and pluralities of receive antennas. The radar transmits a signal modulated with spread codes that are information bits. A receiver discriminates the signals sent from own transmitters and multiple reflections to detect objects of interest. In addition, the receiver discriminates signals transmitted from different systems on other vehicles. This requires the receiving system to have knowledge of the codes transmitted by the other vehicle. The receiving system determines the information bits sent by the other vehicle. If multiple radar systems on multiple vehicles use different sets of codes (but known to each other), the multiple systems can create a communication infra-structure in addition to radar detection and imaging.

  • Patent number: 9915730
    Abstract: A method and system for generating an image of a scene behind a wall, wherein the scene is represented as a grid, by first transmitting a radar pulse through the wall using a transmitter and receiving a set of echoes corresponding to the radar pulse being reflected by the scene in a receiver at a known location. Based on the location, an imaging operator that relates the set of echoes to the grid is determined. Using the imaging operator, a sparse delay kernel that matches a response of a current image to a similar response in the set of echoes is determined. Then, the current image is updated, based on the set of echoes, the imaging operator, and the sparse delay kernel. The transmitting, the receiving, the determining, the obtaining, and the updating steps are repeated for different locations until a termination condition is reached.

    Abstract: A target detection apparatus includes a first target detection section which detects a target which exists ahead of a vehicle and has a height sufficient to strike against the vehicle; a second target detection section which detects the target in an area different from an area in which the target is detected by the first target detection section, and a reliability degree setting section which sets a target reliability degree indicating probability that the target exists. When the target is detected only by the first target detection section or the second target detection section, and after the target is detected by both the first and the second target detection sections, the reliability setting section sets the target reliability degree based on an overlap detection time which is a period of time during which both the first and the second target detection sections continuously detect the target.

  • Publication number: 20150077282
    Abstract: A combination of active reader tags and ultra wideband (UWB) radar systems provide real-time monitoring of first responders, with identification of each team member using active tags, and detection of victims or other subjects using motion or breathing detection, in a field of operations such as a building affected by fire or hazardous material or search and rescue mission area. Initially, a cluster of miniaturized radars (sensors) act in a static mode of operation, gathering static radar information used to depict a constructed layout of the premises. The cluster of radars then operate in a dynamic mode that detects motion or breathing of multiple subjects inside the field of operations. With dual mode operation the system can read the active tags identification, and by triangulation, display the position of each first responder with its identification and positions of subjects on a composite image of the constructed layout.

  • Publication number: 20150054672
    Abstract: A radar signal processing device is provided, which performs a scan correlation in a polar coordinate system to secure accuracy of the scan correlation, and prevents a suppression of a target object moving at high speed due to the scan correlation. A polar coordinate correlator performs, in a polar coordinate system, a correlation between reception data and previous correlated data stored in a previous data storage. A trend curve calculating module calculates a trend curve of a distance-direction signal level of the reception data in the polar coordinate system. A target detecting module detects a target based on the signal level of the reception data and the trend curve. Further, the polar coordinate correlator changes the contents of the correlation of the reception data based on the target detection result from the target detecting module.
