The casing in the gas-filled condition assumes the form of a balloon with a cylindrical sidewall. Inside the casing there are four stripes made of metallised polymeric film, interconnected along the longitudinal edges. Other longitudinal edges of the strips are attached to the inner surface of the casing so that, when filling the casing with helium they form a four-bladed structure of the reflector (1) of the radar impulse having mutually perpendicular planes. The casing with a flexible tube (5) is connected to the balloon with providing quick-release coupling. Inside the casing, a return valve (4) is mounted.
