| 41 | APPARATUS AND METHOD FOR RAPID DETECTION OF OBJECTS WITH TIME DOMAIN IMPULSIVE SIGNALS | EP04785729 | 2004-03-12 | EP1601990A4 | 2008-01-23 | MCLEMORE DONALD P |
| A method and system are disclosed for detecting objects of interest in a target area using ultra wide band (UWB) RF signals. A transmitter and antenna array generate ultra wide band RF impulsive signals that are used to probe a target area that may include an object of interest. An antenna and a signal processor receive return signals from the target area and process the return signal to generate a set of coordinates. The coordinates of the processed return signals are compared to coordinates of known objects in a pre-existing database to determine whether there is a match between the return signal and a known object. When there is an indication of a match, the existence of the known object is displayed to an operator of the system. | ||||||

| 44 | SYSTEMS AND METHODS FOR IMPROVING PLATFORM GUIDANCE OR NAVIGATION USING UNIQUELY CODED SIGNALS | EP17168435.0 | 2017-04-27 | EP3239730A1 | 2017-11-01 | HOLDER, Ernest Jefferson |
A spatially-distributed architecture (SDA) of antennas transmits a set of uniquely coded signals. A first receiver having a known position in a coordinate system defined by the SDA receives reflected versions of the uniquely coded signals. A first processor receives the reflected versions of the uniquely coded signals and identifies a position of a non-cooperative object in the coordinate system. A platform having a second receiver receives non-reflected versions of the uniquely coded signals. The platform determines a position of the platform in the coordinate system. In an example, the platform uses a self-determined position and a position of the non-cooperative object communicated from the SDA to navigate or guide the platform relative to the non-cooperative object. In another example, the platform uses a self-determined position and information from an alternative signal source in a second coordinate system to guide the platform after a coordinate conversion.
