Abstract: A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) having a ramjet providing supersonic cruise of the UAV. Deployable antenna arms support a passive radar receiver for bistatic reception of reflected radar pulses. The UAV operates with a UAV flight profile in airspace beyond a radar range limit. The deployable antenna arms have a first retracted position for supersonic cruise and are adapted for deployment to a second extended position acting as an airbrake and providing boresight alignment of the radar receiver. A mothership aircraft has a radar transmitter for transmitting radar pulses and operates with an aircraft flight profile outside the radar range limit. A communications data link operably interconnects the UAV and the tactical mothership aircraft, transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna to the mothership aircraft.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for multiple access to a channel carrying a common uplink burst transmitted by users that utilize two different modes. Specifically, a coupled mode provides for range extension for users at a cell edge, while a decoupled mode provides for user data transmissions within the common uplink burst. Multiple access between these different modes may be provided in a non-orthogonal scheme by moderating the amount of interference between the respective modes. Further, multiple access between these different modes may be provided in an orthogonal scheme by utilizing interleaved frequency division multiple access (IFDMA).

Abstract: Apparatus, systems, and methods are disclosed for determining dynamic positioning of mobile cells. Dynamic positioning provides for navigating a mobile cell, such as an unmanned aerial vehicle or the like, to a location suitable for offloading current network traffic, such that the suitable location maximizes offloading capabilities. The methodology describes takes into account both the current traffic load on the network and the location of the highest system capacity-intensive mobile terminals in determining an initial position for deploying the mobile cell. Additionally, the location of the deployed mobile cell is optimized, over time, based on tracking the direction of movement of the highest capacity-intensive mobile terminals, and, in some embodiments, service quality indicators provided by the mobile terminals and/or contextual information captured by the mobile cell apparatus.

Abstract: A system and method for optimizing a rescue operation of an individual. The method comprises maintaining, by an individual engaged in an activity, an unmanned aerial vehicle (UAV) associated with and in proximity to the individual. For storage at the UAV, the individual records at a recording device a message. A sensor device is configured to detect a situation requiring a need to rescue the individual at a current location, and generates a trigger signal in response to a detection. In response to the receipt of the trigger signal, a current GPS location of the individual is recorded and a launching of the UAV to traverse a flight-path to a destination location. At or before arriving at the destination location, the UAV contemporaneously provides the stored recorded message and current GPS location of the individual to an emergency response authority to inform of the individual's situation and location.

Abstract: A method of recovering communication transmission function of an aerospace vehicle. In operation, a remote control center receives, from a ground-based station, a request of recovering the communication transmission function of the aerospace vehicle being in operation and not on a ground. The request includes positioning information of the aerospace vehicle. In response to the request, the remote control center sends an instruction to an unmanned aircraft vehicle (UAV) in air. The UAV functions as an electromagnetic wave transmission relay station, and the instruction includes the positioning information of the aerospace vehicle. Thus, the UAV may track the aerospace vehicle according to the instruction, and establish a two-way communication between the remote control center and the aerospace vehicle via the UAV as the electromagnetic wave transmission relay station. Thus, the remote control center may perform recovery of the communication transmission function of the aerospace vehicle via the UAV.
