1. An air-cooled cooling structure comprising:
a base plate;
a radome attached to the base plate;
a first heat transfer member attached to the base plate in a space formed by the radome and the base plate;
an internal fan that generates an air flow to the first heat transfer member in the space;
a fixing member that serves as a support member that supports a plurality of antenna substrates and a signal processing unit in the space and a ventilation guide that guides the air flow along the signal processing unit; and
a second heat transfer member attached to the base plate, the second heat transfer member being thermally coupled to the first heat transfer member at a face facing an attachment face of the first heat transfer member.
