A sensor (20) for a missile seeker includes a primary, concave, reflector (40) that is reflective to RF waves (70) and to another kind of waves (90), but that includes a transmissive region (100), through which RF waves (70) can pass. A secondary, convex, reflector (50) is reflective to RF waves (70) but transmissive, and not reflective, to the other kind of waves (90), and is arranged facing the primary reflector (40) to further reflect RF waves (70) reflected by the primary reflector (40) through the transmissive region (100) of the primary reflector (40). An RF detector (60) is arranged on the opposite side of the primary reflector (40) from the secondary reflector (50) and arranged to detect the RF waves (70) reflected by the secondary reflector (50) through the transmissive region (100) of the primary reflector (40). A second detector (80), for detecting the other kind of waves (90), is arranged on the opposite side of the secondary reflector (50) from the primary reflector (40) and is arranged to detect the other kind of waves (90) after they are reflected by the primary reflector (40) and transmitted through the secondary reflector (50). |
