Adding Communications Mode Capability in the Periscope Detection Radar (PDR) Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-076 Topic Title: Adding Communications Mode Capability in the Periscope Detection Radar (PDR) Proposal No.: N121-076-0183 Firm: 3 Phoenix, Inc. 14585 Avion Pwy Suite 200 Chantilly, Virginia 20151 Contact: Bob Smarrelli Phone: (703) 956-6480 Web Site: www.3phoenix.com Abstract: This proposal describes a low-cost real-time network for sharing the Anti-Submarine Warfare (ASW) Common Tactical Picture. An architecture is proposed that uses the SPS-74 Periscope Detection Radar (PDR) as a broadcast transmitter and a low-cost digital receiver system that is installed on all participating units. A technical description is provided for the key components of the transmit and receive subsystems including estimation of key performance parameters. The system proposed is shown to have data communication capability comparable to Link 16 and is expected to be far less expensive than integration of the radar and tactical decision functions with existing combat systems and tactical data links. Benefits: This capability, when fully developed, will provide a significant improvement to the tactical posture of the ASW task forces. The obvious commercialization application is to transition to the SPS-74 system for fleet deployment of the radar communications capability. Periscope detections from the SPS-74 will be propagated automatically to escort platforms for prosecution. In addition, this technology has the potential to interface with new systems being developed including the MH-60R to support the ASW kill-chain. Finally, because this communications channel is not envisioned to be fully utilized, it may support high-speed communication of other tactical data types between platforms in satellite restricted coverage areas.
