Summary:PURPOSE:To realize a small combined seeker which comprises a plurality of sensors such as a passive and an active rader. CONSTITUTION:A combined seeker comprises a passive rader 12 which detects a target by receiving electric waves from it and an active rader 14 which radiates electric waves and receives their reflected waves to detect the target. The receiving surface of a spiral antenna used in the passive rader for reception of electric waves is concave so that the spiral antenna 11 acts as a reflector for the active rader 14. Electric waves radiated by the active rader 14 are reflected on the receiving surface and the radiated into the air.
