COMbine BAground multi-band Target-Scene Projector (COMBAT-SP)

Physical Sciences Inc. (PSI) has been awarded a program from the Naval Air Warfare Center to develop a COMbined BAckground multi-band Target-Scene Projector (COMBAT-SP) to address the Navy’s need to simulate countermeasure performance through hardware-in-the-loop (HWIL) testing.

The key innovation of PSI’s approach is the use of modified Digital Micromirror Devices to create flickerless target sources with high apparent temperature and controllable multi-spectral infrared signatures. The COMBAT-SP system includes an imbedded, opaque primary target aperture in a wide field simulated sky background and an ultraviolet/visible and infrared split band beam combining and steering concept. The split band beam combination allows for steering of a translucent secondary target against the fixed primary target and sky background.

Anticipated benefit of the COMBAT-SP is an extension of existing infrared target generation table capabilities including high temperature, controllable multispectral sources, and the addition of a wide field ultraviolet/visible background. PSI’s system will be beneficial for HWIL testing to facilitate next generation, seeker and counter measure development. HWIL provides crucial end-to-end system testing that is not afforded by direct injection of targets into focal plane arrays. Furthermore, the architecture of the COMBAT-SP is flexible and customizable to a wide array of units under test and testing platforms. The technology could also be used to test next generation electro-optical and infrared sensors with applications outside of munitions testing.
