摘要： A radar system includes a radio frequency (RF) section that is controllable to focus operation in one of a plurality of fields of view (FOVs) and a control section configured to identify a side of the vehicle in which the radar system is installed and direct the RF section to focus transmission and reception in one of a first or a second FOV based on the side of the side of the vehicle in which the radar system is installed. A method includes: transmitting RF energy and listening for a reflection from a predetermined target mounted on one side of a vehicle; determining a whether a reflection has been detected; and directing the RF section to focus operations to the FOV that is predetermined for use for a radar system mounted on a same side of the vehicle as the predetermined target when a reflection has been detected.

摘要： An each pattern is provided a reception pathway, the method uses the synchronous replies and the asynchronous replies, unsolicited of Fruit type, transmitted by targets present in the aerial environment of the radar and detected over a given number of antenna revolutions. At each detection of a reply the value of its off-aim in bearing and the value of relative power received on each of the pathways are calculated as is its elevation by extrapolation with the synchronous detections close to the same target and associated with the detection. The values obtained over the given number of revolutions are stored, the measured patterns being sampled on the basis of the stored values.

摘要： 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.

摘要： The RF system for preventing hunting accidents comprising RF interrogator mounted on the firearm or hunter's hat and RF transponder attached to hunter's hat, wherein directional pattern of antennas of the hat-mounted interrogator is directed along the line of view of the hunter so matching with sightline of hunter's rifle; and RF transponder, which, to cover directional pattern of 360 arc degrees in azimuth, contains a number of RF transceiver evenly attached to the hunter's hat in horizontal plane and connected to the single electronic unit. The system provides alert information about “friendly targets” that could be under fire, such as other hunters or persons equipped with said transponder; and if they are, the system develops alert signal: “Do not shoot”.

摘要： The present invention includes a method for identifying a facility on the ground or at sea, the method being implemented on an airborne responder linked to at least two antennas, the method including a step of choosing a first transmission antenna and a step of transmitting an interrogation message from the chosen antenna. The method further includes testing whether a response has been received by the responder, and, if at least one response signal is received by at least one of the antennas, choosing a transmission antenna as a function of the response signal or signals received. If no response message is received, a different transmission antenna is chosen from the antenna that transmitted the last interrogation message. The method is repeated from the step of transmitting the interrogation message.
