Low SWaP Tactical Ultra-Secure Communications System

Spectric Labs and Motorola Solutions (MSI) present, ATHERIS, a low probability of intercept/low probability of detection (LPI/LPD) waveform to facilitate terrestrial and SATCOM communications on a low Size, Weight, and Power (SWaP) system. Our solution utilizes Spectric Labs’s state of the art waveform design and Motorola’s proven experience developing and delivering low SWaP radio platforms (TRL-9) to host LPI/LPD waveforms. The ATHERIS waveform design achieves LPI/LPD characteristics by implementing a wideband, frequency agile signal along with a combination of techniques to remove cyclic properties from the underlying signal. Our approach is built upon our success designing and evaluating a low-cost LPI/LPD system, URSINI, for the Army SPARTN program. The ATHERIS waveform incorporates several novel techniques which include Distributed Carrier frequency hopping modulation, chaotic phase spreading, and custom optimized pulse shape filters (PSFs) to produce an ultra-secure waveform. This unique combination will provide SOCOM with a flexible LPI/LPD capability that can feasibly be implemented on both existing and new software defined radio hardware platforms.
