Abstract: A device and method of avoiding future self-interference are described. During a current predetermined time period, a priori knowledge of an RF environment is used to determine a change in the environment in a next predetermined time period. Transmission on an interfering channel in response to the change leads to generation of an indication to another device to switch communications in the next predetermined time period to a new channel that is unaffected by transmission on the interfering channel. The new channel is set by the indication or is negotiated by the other device from a list of channels to use in the indication.

Abstract: A system includes a library of elements to create a model describing a waveform parameter technique. A constraint checker verifies that the created model is correct by construction by needing no verification after compilation. The constraint checker also implements a valid programmable device build according to the waveform parameter technique. A placement decision module receives the verified models produces a placement decision for placing the waveform parameter technique based on the verified model in a programmable device. A synthesis tool receives the verified model from the placement decision module and synthesizes the waveform parameter technique based on the verified model. A link/loader receives the placement decision from the placement decision module and receives the synthesized technique from the synthesis tool. The link/loader also places the waveform parameter technique in the programmable device according to the placement decision.

Abstract: A system for controlling an active electronically scanned array (AESA) antenna, which enables the AESA antenna to switch rapidly between different antenna states, includes memories (38) connected to a common address bus (40). Each memory (38) is also connected to a digitally controlled RF signal transmission block (32) within the AESA antenna, and stores digital control words for the digitally controlled RF signal transmission block (32). When a new address is provided on the address bus (40), each memory (38) outputs a new digital control word to its respective digitally controlled RF signal transmission block (32), causing a change in the state of the AESA antenna.

Abstract: Disclosed subject matter relates to techniques for allowing multiple transmit/receive assignments to share antenna resources in an efficient manner. The techniques may be used with, for example, transmit/receive assignments that are non-deterministic in nature. In some implementations, transmit/receive assignments each have a corresponding priority value. Transmit/receive assignments are permitted to contend for available antenna resources based, at least in part, on priority.

Abstract: Provided is a system and method for tracking and identifying a target in an area of interest based on a comparison of predicted target behavior or movement and sensed target behavior or movement. Incorporating aspects of both particle diffusion and mobility constraint models with target intent derivations, the system may continuously track a target while simultaneously refining target identification information. Alternatively, the system and method are applied to reacquire a target track based on prioritized intents and predicted target location.

Abstract: A system for transferring power and/or data through a skin of a vehicle includes a first module for disposition on an external surface of the vehicle, a first magnet arrangement attached to the first module, a second module for disposition on an internal surface of the vehicle, and a second magnet arrangement attached to the second module. The first magnet arrangement and the second magnet arrangement are selected to provide sufficient magnetic attraction therebetween to maintain the first module at a fixed position on the external surface of the vehicle by overcoming an air load force when the vehicle is in motion. When the first module and the second module are in registration with each other though the non-ferrous skin, at least one inductive coupling circuit through the non-ferrous skin is formed to provide one or more bidirectional paths therebetween for transfer of data signals, electrical power or both.

Abstract: A system and method for determining the geolocation of a signal emitter moving at an unknown velocity by combining signal data of a target detection platform (e.g., a radar system) and signal data collected by two or more moving signal collection platforms (e.g., RF signal receivers). In one embodiment, the target detection platform determines tentative location and velocity of the signal emitter, and the signal collection platforms are configured to perform TDOA and/or FDOA analysis of the collected signal data corresponding to a signal of the signal emitter. In one embodiment, solutions provided from the TDOA and/or FDOA analysis are unbiased by using the tentative velocity of the signal emitter, and the geolocation of the signal emitter is determined by matching the TDOA/FDOA solutions and the detected tentative location.
