AbstractThe problem is to design and develop a multi-spectral screen for HWIL laboratories which is reflective in the infrared (IR) and transmissive in the microwave region. This SBIR proposal describes four new design approaches developed at Pacific-Sierra Research Corporation for such a dichroic screen. The first technique uses a stationary, dielectirc screen with a conic surface and small IR reflective squares on an RF transmissive dielectric screen to reflect the IR and transmit the RF wave through the dielectric. The second technique uses an RF transmissive dielectric screen with a quarter wave IR coating on the flat screen to reflect the IR and transmit the RF wave through the dielectric. The third technique uses a screen composed of phyllosilicate minerals that are transmissive in the RF and reflective in the IR. The fourth technique uses an agile, IR fiber-optic, RF dielectric bundle to relay an IR source image to a dielectric IR collimator which projects a collimated IR image to the missile. The RF propagates through the dielectric fiber bundle and IR dielectric collimator. The technical objectives listed for Phase I are structured to provide a detailed technical design and measurements that can be used to fabricate, test, and deliver a multispectral target screen in Phase II.
