DAHLGREN, Va. (NNS) -- Naval Surface Warfare Center (NSWC) Dahlgren Division Commander Capt. Sheila Patterson signed a Cooperative Research and Development Agreement (CRADA) with Northrop Grumman (NG) at a signing ceremony here, Sept. 6.

This agreement enables integration of the Navy’s accurate system timing and precision platform self-location capabilities with Northrop Grumman’s electronic surveillance enhancement (ESE) to the surface ship AN/SLQ-32(V) electronic warfare system.

"This CRADA is important because it provides for the cooperation of government and industry on a problem of great importance to Sailors,” said Reuben Pitts, NSWC Dahlgren's Warfare Systems Department head. “The resources of NG and the surface warfare center can be applied with results in synergy to unlock the potential of evolving timing technologies."

The Navy is developing a family of future surface combatants - DDG-1000, LCS, CVN-21 and CG(X). The concepts of operation for these new classes are transformational, employing new warfare techniques in a net-centric environment.

The CRADA effort will directly support the Chief of Naval Operations’ need for these transformational ships to operate in a carrier strike group as a distributed and self-synchronized combat system. Net-centric capabilities that require precise time include bi/multi-static applications, signal processing, pulse classification and geo-location techniques. Further, precise common time on a platform can reduce the number of antennas required for electronic warfare, as well as attendant weight, space and power savings.

The objective of this research project is twofold. First, to define the data processing, algorithms and hardware requirements necessary to provide near real-time precision common time capabilities, and second, to tactically apply this capability in an at-sea demonstration following rigorous testing ashore.

To validate tactical utility in current shipboard and future Electronic Warfare (EW) systems, a shipboard EW hardware-in-the-loop system proof of concept and post experiment analysis will be conducted. The results of this analysis will be tested in a real-time mobile platform scenario over a long baseline.

This cooperative engineering will result in a precision time interface to a common time standard enabling the demonstration of multi-platform emitter correlation and geo-location.

This work will be conducted at both NSWC Dahlgren and NG Integrated Systems’ Land-Based Test Site and ESE production facility in Goleta, Calif., in order to verify and validate electronic surveillance (ES) technique and control effectiveness for single and multi-platform use.

NSWC Dahlgren will perform modeling and simulation to quantify benefits of employing advanced ES techniques and controls.

The CRADA’s duration is for three years.
