===> 위에 소개한 기사 이전에 5 월에 소개되었던 LSRS 에관한 기사와 기사중에 인용되었던 하픈 유도관련 보잉사 소개보도문입니다. 재미있는 것은 이 레이더는 AESA 이지만 P-8 에 장착되는 AN/APS-10 레이더는 능동형이 아니라 수동형 위상배열 레이더입니다. 물론 AN/APY-10 는 LSRS 처럼 육상 이동표적 추적능력은 없는 해상감시용 레이더입니다. 그래도 해상 탐지거리가 P3C 에 장착된 AN/APS-137 보다 훨씬 크네요
중량은 훨씬 작은데 말입니다.

Not-Quite-Secret Radar

New to the not-quite-secret file is the Raytheon-Boeing Littoral Surveillance Radar System (LSRS), a wide-aperture active electronically scanned array (AESA) surveillance radar that is now operational on P-3 Orions flown by VP-46 out of Whidbey Island. LSRS has been used in exercises in the Pacific and operationally in Southwest Asia. It's been mentioned in Jane's and a number of spotter sites, notably the Netherlands-based P-3 Orion Research Group which estimates that at least five aircraft have been modified.

The Boeing-Raytheon team -- the program's umbrella name is Advanced Sensor Technology (AST) -- accomplished 2800 hours of testing, apparently based at Love Field in Dallas, before achieving early operational capability in 2005, according to this official publication (pdf, last page).

LSRS is designed to provide targeting-grade tracking of moving targets on land and at sea. In September, one of the LSRS P-3s supported a test of the Navy/Boeing SLAM-ER missile against a moving target, a simulated SA-10 missile launcher, at China Lake; follow-on tests were to use the same combination of systems against a maneuvering ground target. In 2010, LSRS is due to support a large-scale Joint Surface Warfare (JSuW) demonstration, providing targeting updates to air- and ship-launched weapons ranging from JDAMs to Harpoons.

Raytheon's role in LSRS is an upset of Northrop Grumman, which had previously dominated Navy trials of moving target indication (MTI) radars through the Gray Wolf and Hairy Buffalo demonstrations. (Both were Norden-legacy programs, Gray Wolf on an S-3 and Hairy Buffalo on a P-3.) LSRS presumably uses the "tile" AESA technology used successfully on the Super Hornet and JSF radars and also has high-resolution synthetic aperture radar (SAR) modes.

But the impact of LSRS may run beyond the Navy. In early 2003, Boeing changed its proposed design for the Multi-Mission Maritime Aircraft (MMA), using the 737-800 as the basis for the aircraft instead of the shorter-bodied 737-700. (MMA is now the P-8A Poseidon.) At the same time, Boeing located the MMA's weapon bay in the rear fuselage. The change was to accommodate a specific, classified capability, Boeing said. Given that Boeing is on the LSRS team it is not hard to guess what that capability is. The long, shallow LSRS antenna is sized for the P-8A's long, low-slung forward fuselage.

Meanwhile, the USAF's planned follow-on to the E-8 Joint STARS, the E-10A, was canceled in the FY2008 budget, and the USAF is still studying the cost of adapting the E-10's radar to the JSTARS platform. With LSRS, though, the P-8A is a modern, long-range, jet-powered platform with an AESA MTI radar and the necessary back-end systems - computers, operator consoles and communications - to support it. Moreover, the USAF has increasingly been evaluating the Joint STARS in the maritime and littoral environment.

Boeing Scores Direct Hit in SLAM-ER Land Moving Target Test
ST. LOUIS, Oct. 05, 2006 -- Boeing's [NYSE: BA] Standoff Land Attack Missile-Expanded Response (SLAM-ER) weapon system scored a direct hit against a moving, remotely-controlled land target during a recent flight test at the U.S. Naval Air Warfare Center, China Lake, Calif.

The test occurred on Sept. 13 as part of the U.S. Navy's SLAM-ER developmental/operational flight test program. The launch followed a successful developmental test flight on June 1 that used simulated command and control aircraft targeting data to engage a remotely-controlled Shahab 3 missile launcher mock-up.

"SLAM-ER now has the flexibility to engage both fixed and moving land targets," said Boeing Naval Weapons Director Jan Browne. "This demonstrated capability greatly enhances the Navy's ability to engage high-interest mobile targets in today's varied threat environment."

For the test, a Littoral Surveillance Radar System-equipped aircraft sent real-time targeting data to the Boeing-built F/A-18 aircraft, which relayed the data to the SLAM-ER after the weapon's launch. The SLAM-ER acquired and impacted a simulated SA-10 missile launcher in a desert environment. A follow-on test will launch the SLAM-ER against a simulated SA-3 missile launcher that will maneuver and change speeds like an operational target.

SLAM-ER is a highly adaptable day/night, all-weather, over-the-horizon precision strike missile capable of hitting stationary or moving targets on land or at sea. The Navy recognizes SLAM-ER as the most accurate weapon in its inventory.

The Navy will complete its operational testing of SLAM-ER's moving target capability later this year.
