Abstract

The invention relates to an all weather visual system that combines information from a ROSAR type radar sensor with navigation and flight information to provide artificial vision for the pilot. The radar utilizes the movements of rotating arms fixedly mounted on the rotor head of a helicopter. For this purpose, a turnstile is used as the central carrier structure, which is protected by an aerodynamically shaped body against atmospheric forces. The radar transmitter and radar receiver are located on the rotor head and in the tips of the rotating arms, respectively.
