    Abstract: A hybrid RADAR and communication system provides both RADAR and wireless communication (COMMS) that share the same antenna, transmit and receive amplifiers, and other hardware, thereby reducing size, weight, and power requirements. In embodiments, COMMS implementation only requires adding additional software to a RADAR system. Embodiments are EW/COMMS systems that provide electronic warfare and wireless communication. EW/COMMS embodiments facilitate communication in hostile environments by enabling data exchange at any frequency within a broad EW frequency range. Communication signals can be obfuscated by interleaving them with EW waveforms at the same RF frequency. Collaborative communication between EW systems is enhanced by reducing EW communication lag times. Systems with physically distinct broadband and narrow band receivers can negotiate data exchange timing and frequencies by exchanging low power, low data rate control signals that are detected by the broadband receiver, while subsequent high density data bursts are received by the narrowband receiver.

    Abstract: Systems are disclosed for navigating a missile to a target using a fixed sensor onboard the missile. In an embodiment, a system includes a launch platform traveling a pre-programmed route to deliver the missile within an area. The missile travels a first flight path through the area in effort to detect targets. If no targets are detected along the first flight path, the missile transitions to a second flight path, different from the first flight path, to locate targets off-axis relative to the first flight path. While the missile travels the second flight path, the sensor receives signal identifying a target located at a position off-axis relative to the first flight path. The missile then adjusts the second flight path to direct the missile to the target. In an example embodiment, the first flight path is straight or arced, while the second flight path is u-shaped, corkscrew-shaped, or spiral-shaped.

    Abstract: Techniques are provided for vision-based altitude estimation using one or more platform mounted cameras. An embodiment includes generating projected ground imagery of imagery provided by cameras of the platform, the projection based on a hypothesized altitude. The method also includes obtaining reference ground imagery based on the location of the platform, the location based on platform navigation data. The method further includes registering the projected ground imagery to the reference ground imagery and generating a match score associated with the registration. The method further includes selecting the hypothesized altitude as the estimated altitude based on the match score (e.g., if the match score exceeds a threshold value or is maximized over a set of hypothesized altitudes. The method may further include otherwise adjusting the hypothesized altitude and repeating the altitude estimation process based on the adjusted hypothesized altitude to search for an improved estimated altitude based on the match score.

    Abstract: A modular electronic warfare (EW) framework that is implemented into a first preexisting EW system with associated hardware and firmware to leverage the capabilities of the first preexisting EW system into a second, different preexisting EW system with associated hardware and firmware. The modular EW framework includes a tracking framework and a logic framework. The tracking framework is configured to receive a first set of objects from a preexisting EW system and augments the first set of objects with at least one parameter and outputs the second set of objects. The logic framework is configured to receive the set of second objects from the tracking framework and implements at least one process onto the second set of objects and outputs a third set of objects. A multi-core processor is used to operate the modular EW framework. The multi-core processor is configured to execute the at least one parameter to output the second set of objects and configured to execute the at least one process to output the third set of objects The first set of objects in the fixed EW system remains unaffected within the fixed EW system. The first set of objects is different than the second and third sets of objects. The modular EW framework is also platform-agnostic and can be implemented with a broad suite of computer processing units and operating systems. Each of the tracking framework and the logic framework of the modular EW framework are asynchronous.
