Terma Demonstrates Small Target Detection Capability Aboard Stiletto


Terma, announced this week how SCANTER 6000 X-band Naval Surveillance Radar performed in the USA, detecting small targets during formal testing on the Stiletto, the U.S. Department of Defense’s experimental craft operated by Naval Surface Warfare Center Carderock (NSWCCD), Combatant Craft Division.

The SCANTER 6000 (SC6000) successfully detected and tracked a high-speed 7m RHIB under various maneuvering scenarios. The same success was exhibited for simultaneous shipping and navigation, and overtaking and passing of vessels under various test conditions. The SC6000 was using a 12’ fan beam antenna with upgraded processor and software during the test sessions.

Operating under a Limited Purpose Cooperative Research and Development Agreement (LP-CRADA) with NSWCCD, Terma conducted the formal testing September 16-18 in the southern section of the Chesapeake Bay, in and around the Chesapeake Bay Bridge Tunnel. The targets used for the testing were a radar reflector (radar cross section (RCS) of .1m2 for X-band) to simulate person in the water, a 3M RHIB (RCS of .4439m2) to simulate a real world, capsized boat, and a periscope-like object (RCS of .5m2) protruding 3-4 feet out of the water.

According to Jim Moore, Terma’s Director of Radar Systems: “The main purpose of the testing was to demonstrate the capability to reliably and consistently detect and track extremely small surface contacts. We tested this with the targets by themselves and in a more challenging scenario of placing them in close proximity to a large contact. In this case, we located them within 50 m of the Chesapeake Bay Bridge Tunnel.”

Moore said of the successful results: “We were able to gather data useful to the continued refinement of the tracker and also document the outstanding performance of the SCANTER 6002 radar as tactical surveillance radar in a naval shipboard environment.”
