STATEMENT OF WORK

LOW BACKGROUND INFRARED (LBIR) SERVICE CONTRACT

1. BACKGROUND

Ground based Mid-Course Defense (GMD) and Aegis SM-3 interceptors systems use Kill Vehicle

(KV) sensor-seekers to discriminate and intercept lethal objects launched via intermediate range and intercontinental ballistic missiles. Effective discrimination and targeting requires KV onboard sensors to accurately measure the radiometric characteristics of potential targets. To ensure accurate performance, KV sensors are characterized during production with Raytheon Missiles &

Defense (RMD) Low-background Scanning Point Source (LSPS) test chambers. Also, KV mission scenario testing is performed by John Hopkins University Applied Physics Laboratory

(JHU-APL) Infrared Seeker Space Calibration and Test (ISSCAT) chambers, Arnold Engineering

Development Complex (AEDC) test chambers, and Next Generation Intercept (NGI) test chamber.

These laboratories use blackbodies and also infrared emitter arrays to test and evaluate the KVs.

These sources provide the stimuli to the KV that simulates the infrared signatures of objects in the threat scene. The emitter arrays provide the KV with complex real-time scene generation. This enables the testing and evaluation of the KV guidance algorithms and the KV discrimination between reentry vehicle, debris, and countermeasures.

To ensure that these test chambers provide consistently repeatable and accurate measurements, thus ensuring consistent KV sensor measurement results from year to year, periodic calibration using measurement/calibration standards is required. These calibration standards must be traceable to the System International (SI) units of radiometric power and wavelength as maintained by the National Institute of Standards and Technology (NIST).

The Air Force Metrology and Calibration (AFMETCAL) established the Low Background

Infrared (LBIR) facility at the NIST, and serves as the Department of Defense (DOD) Missile

Defense Agency (MDA) executing agent for the facility. The LBIR Facility located at the NIST

Sensor Science Division in Gaithersburg, MD provides the infrared user community with a calibration base that includes both spectral and broadband measurements in a 20 K background environment. The spectral calibration capability is currently developed in three areas: spectral calibration of low-background infrared detectors, characterization of optical components, and three cryogenic transfer radiometers, Ballistic Missile Defense Organization (BMDO) Transfer

Radiometer (BXR), Missile Defense Transfer Radiometer (MDXR) and User Transfer Radiometer

(UXR) used to evaluate highly collimated infrared sources (e.g. Test Chambers) such as those located at RMD, JHU-APL, AEDC and NGI. The broadband measurements are performed for the calibration of blackbodies in radiance mode.
