COVER

摘要

A cover assembly is provided, for use with an instrument package having a common aperture. The cover assembly includes an inner cover member and an outer radome member. The inner cover member is substantially transparent to electromagnetic (EM) radiation of at least a first wavelength range. The outer radome member is configured for selectively and reversibly covering the inner cover member and transparent to EM radiation of at least a second wavelength range different from the first wavelength range. The second wavelength range includes a radio frequency (RF) wavelength range. The outer radome member is configured for being mounted in overlying relationship with respect to the common aperture of the instrument package. The outer radome member is configured for being initially in overlying relationship with respect to the inner cover member and for being selectively removed from the overlying relationship with respect to the inner cover member at least during flight conditions.
