20090135065 | Object Detecting Apparatus and Method for Detecting an Object - An object detection apparatus includes a radar means that detects the position of an object; an imaging means that detects the position and size of an object; a fusion processing means that fuses the object detected by the radar means and the object detected by the imaging means as the same object, when the detection results of the radar means and the imaging means satisfy a prescribed fusion condition, to generate a fusion object having position information and size information. A provisional fusion object is generated if the detection result from the imaging means does not satisfy the fusion condition with respect to the detection result from the radar. | 05-28-2009 |
20090140925 | Multilateration Enhancements for Noise and Operations Management - Multilateration techniques are used to provide accurate aircraft tracking data for aircraft on the ground and in the vicinity of an airport. From this data, aircraft noise and operations management may be enhanced. Aircraft noise may be calculated virtually using track data in real-time and provided to a user to determine noise violations. Tracking data may be used to control noise monitoring stations to gate out ambient noise. Aircraft emissions, both on the ground and in the air may be determined using tracking data. This and other data may be displayed in real time or generated in reports, and/or may be displayed on a website for viewing by airport operators and/or members of the public. The system may be readily installed in a compact package using a plurality of receivers and sensor packages located at shared wireless communication towers near an airport, and a central processing station located in or near the airport. | 06-04-2009 |
20110140968 | A LEAN V2X SECURITY PROCESSING STRATEGY USING KINEMATICS INFORMATION OF VEHICLES - A vehicle-to-vehicle communication filtering system is provided to selectively process broadcast messages between a host vehicle and a remote vehicle. A processing unit evaluates a time-to-collision status between the host vehicle and the remote vehicle sending the message. The time-to-collision status is a function of a relative distance and a relative velocity between the host vehicle and the remote vehicle which are determined from data provided within a first portion of the message received from the remote vehicle. An attentive factor is assigned to each of the remote vehicles based on the time-to-collision with respect to each remote vehicle. The attentive factor identifies a proportion of messages broadcast from the remote vehicle to be targeted for security processing. Security processing of the message is performed based on a second portion of the message unless the attentive factor indicates the message should be ignored. | 06-16-2011 |
20130050024 | BISTATIC RADAR SYSTEM USING SATELLITE-BASED TRANSMITTERS WITH IONOSPHERIC COMPENSATION - A system for the passive location of non-cooperating vehicles using satellite-based transmitters with ionospheric compensation. The system is a light-weight, low-cost, portable, and field-deployable station to supplement deficiencies in the National Airspace System (NAS) and homeland security surveillance networks. The system accommodates observation modes having long “integration” times that potentially are greater than one second. The system utilizes satellite-based transmitters as illuminators. The passive system measures two radio waves (e.g., a direct path and an illumination plus reflection path), and applies time-difference techniques that can compensate for the ionosphere since the ionospheric delay is applied to both signals. This also has the advantage of compensating for other uncertainties such as exist in the position of the satellite. | 02-28-2013 |
20140218242 | COMPUTERIZED NANO-SATELLITE PLATFORM FOR LARGE OCEAN VESSEL TRACKING - A tracking system employs a constellation of low earth orbit satellites to receive multiple vehicle tracking signals and based thereon, track within a system grid each vehicle under surveillance. The system can use AIS for ocean going vessels, ADS-B for aircraft, and AEI for trains. Use of the system permits extended tracking of key cargos and the protection of vehicles from piracy and the like. | 08-07-2014 |
20160377709 | DETERMINING AN OBJECT DISTANCE USING RADIO FREQUENCY SIGNALS - An object-tracking system can compute a distance to a target object. During operation, the system can use a radio antenna to receive a first radio signal pattern from a direction of a target object. The system determines a time interval from the received radio signal pattern, and determines a velocity of the local system. The system then computes a distance to the target object based on the time interval and the velocity of the object-tracking device. | 12-29-2016 |
