Abstract: A wideband chaotic waveform that is rateless in that it may be modulated at virtually any rate and has a minimum of features introduced into the waveform. Further, the waveform provided may be operated below a signal to noise ratio wall to further enhance the LPD and LPE aspects, thereof. Additionally, the present disclosure may provide a mix of coherent and non-coherent processing techniques applied to signal samples to efficiently achieve coarse synchronization with a waveform that is faster, more efficient and more accurate than using time domain signal correlators alone.

Abstract: The system and method for position, navigation, and timing and more particularly to a system that is time and/or position independent and capable of autonomous transition from GPS to non-GPS navigation. The integrated position, navigation, and timing system uses primary and secondary navigation sensors and primary and secondary navigation measurement sources with a common time reference architecture, an integrated “dual-grid” navigation module, an integrated “dual-grid” navigation Kalman filter, and an integrated “dual-grid” navigation source selection module to provide both geodetic and relative grid timing and/or location among members of a network of platforms, particularly in GPS denied or degraded environments.

Abstract: A system and method of cognitive radio control to allow for low probability of detection and/or low probability of exploitation communications in a contested or hostile environment. The cognitive radio system of the present disclosure can reason over policy constraints and real-time data to make dynamic changes to mission parameters in real-time.

Abstract: A set of methods for discovery of nodes where at least some of the nodes use directional antennas is presented. The methods consist primarily of partitioning the search space into tiers based on elevation angles and adjusting parameters used to construct tiling patterns and slots for discovery messaging, and search methods patterns. The methods further include partitioning into subslots as well as characterization of HAIL slots and rendezvous slots. The HAIL slots and rendezvous slots are allocated within a search schedule and synched across multiple platforms for greater efficiency of communication.

Abstract: A system and method for controlling a aradio transmitter from the application layer is presented. The method includes monitoring an uplink state of a shared channel at a cell manager and processing the uplink state, at least in part, in the application layer in the cell manager to produce processed uplink state. The processed uplink state is then broadcast in a control packet on a downlink of the shared channel to a subscriber manager. The processed uplink state is then further processed, at least in part, at the application layer in the subscriber manager to produce transmitter control data. The transmitter control data is then used control the radio transmitter.
