FIELD: the invention refers to calibration of multi channel radiolocation antenna in a rocket in time of flight.
SUBSTANCE: the essence of the invention is in that a radiolocation antenna for a guided rocket is calibrated in flight with the help of punctual source of microwave frequency and a lens for emulation of the source of a field in a distant zone. The microwave frequency source and the lens are installed behind a metallic cap in the front end of a fairing not to create interferences in the work of the radar. There are different methods of feeding the punctual source and various variants of fulfillment of the lens.
EFFECT: provides possibility of calibration of radiolocation antenna in time of flight and so elimination of incorrect calibration caused by ageing of components and thermal and mechanical efforts arising at storing and/or launching of a rocket.
