Abstract: A decoy deployment and retrieval system includes an extensible boom and corresponding cradle or saddle for use in the retrieval of the towed decoy such that, upon retrieval, the extensible boom with its decoy captured in the cradle is retracted into a chamber so that the decoy can be deployed over and over again. In one embodiment, the decoy is both towed by, and controlled over, a fiber optic line in which a load cell is used to detect tension on the line to prevent damage, and a fiber optic rotary joint is utilized along with high voltage slip rings to permit electrical and optical coupling without backlash, fouling or damage to the line.

Abstract: A procedure for temporally isolating an environmentally dependent integrated circuit fault includes the steps of determining a marginally failing and a minimally passing environmental condition corresponding to the fault; identifying a clock cycle Tmax at which the fault was first detected; determining a candidate clock cycle at which the fault may have occurred; and iteratively a) applying test pattern subsets from an initial clock cycle through the candidate clock cycle under the marginally failing environmental condition; b) applying remaining test patterns under the minimally passing environmental condition; and c) adjusting the candidate clock cycle based upon whether the fault occurred during test pattern subset application up through the candidate clock cycle under the marginally failing environmental condition. Candidate clock cycle adjustment in accordance with a binary search technique enables determination of an exact clock cycle at which the fault occurred in a maximum of Log2 (Tmaxnull1) iterations.

Abstract: Methods and apparatuses for determining angular information from a target. A plurality of sensors on an image plane are used to obtain measured amplitude data. An azimuth and elevation may be estimated using this measured amplitude data. A residual error between the measured amplitude data and calibrated amplitude data may then be determined. The angular information corresponding to the azimuth and elevation at which the residual error is minimized may then be outputted as representing or corresponding to the angular information of the target.

Abstract: A system is presented that provides real-time performance for iterative multi-user detectors, such as Turbo MUDs, which are used to separate simultaneous transmissions on the same frequency, by permitting the MUD to use a less computationally intense, fast-processing algorithm and to correct for errors caused by the fast processing. In order to reduce the errors, a voting system is coupled to the output of the multi-user detector within the iterative system. The voting system provides confidence values on a bit-by-bit basis for the estimates made by the multi-user detector, with the confidence values then being utilized as soft inputs to a bank of conventional single-user decoders.

Abstract: A switch matrix circuit module for routing signals. In an example, the module includes a switch matrix coupled with first and second switches. The switch matrix is configured to receive a plurality of input signals, and output a selected one of the plurality of input signals as a first intermediate signal and another selected one of the plurality of input signals as a second intermediate signal. The first switch receives the first intermediate signal and a first auxiliary signal, and outputs a first output signal, and the second switch receives the second intermediate signal and a second auxiliary signal, and outputs a second output signal. A number of the modules can be coupled together to provide a switch matrix circuit, which can be readily scaled by adding further modules. In an example, the plurality of input signals are radio frequency (RF) signals.

Abstract: A method is disclosed of efficiently synchronizing time bases of multi-netting network nodes. A first node transmits a synchronizing request on a subnet associated with the highest time quality in its source table, then simultaneously monitors that subnet and up to three additional subnets associated with lower time qualities in its source table. If the first node does not receive a response, it transmits the request on the subnet associated with the next highest time quality in its source table. A second node simultaneously monitors the subnet associated with its time quality and a plurality of subnets associate with consecutively higher time qualities. Upon receiving the synchronization request, it responds on the subnet associated with its time quality. The disclosed method is fully compatible with networks that include single-netting nodes, and can be implemented by a JTRS node exchanging RTT messages on a Link 16 network.

Abstract: A portable launcher to launch a guided projectile at an aerial target, wherein the guided projectile has a projectile guidance kit and a target leading guidance kit that is provided with the guided projectile and the portable launcher. The target leading guidance kit includes a target lead estimation protocol stored on a computer readable media and accessible by a processor of the target leading guidance kit. When the processor executes the target lead estimation protocol, the processor is instructed to dynamically lead a reticle of an electronic sight of the target leading guidance kit from the initial target position to the lead target position in response to the projectile guidance kit detecting a speed of the aerial target and an inertial measurement unit of the target leading guidance kit that measures the slew of the guided projectile from the initial position to the translated position.
