TrellisWare Technologies, Inc. — Department of Defense SBIR Phase I: The attributes that imbue a radar sensor with sufficient resolution to detect a small cros

Description

The attributes that imbue a radar sensor with sufficient resolution to detect a small cross-sectional periscope namely, high gain and high bandwidth motivate a compelling alternative to SATCOM for antisubmarine warfare command and control: radar communications. A dual mode ASW search and communications system could leverage the existing PDR infrastructure to provide a communications capability, thereby assuring C2 connectivity even when SATCOM access is denied. In order to ensure a high probability of transitioning to the fleet, any communications mode capability developed for PDR must comply with three design constraints: (1) minimized ASW search impact, (2) minimized cost, and (3) maximized communications capability. In the program described herein, TrellisWare proposes to leverage its advanced signal processing toolkit e.g., per-surivor processing (PSP) and adaptive iterative detection (AID) as well as a mature, modern forward error correction solution in the design of a dual mode ASW search and communications capability that complies with these design constraints.
