and in nikolai chemhensky, head of the laboratory of radio meters of the continuum, tells the principleof the work of the rotan. sauran, under his leadership , new devices appear at the facility and existing devices are modernized, which help to detect radiation from space, incident on a circular energy reflector from an area of ​​​​several thousand square meters , focuses at different points, first either on a horizontal periscope reflector, or immediately on the so-called irradiators , where secondary mirrors with signal receivers are installed. that's all what is reflected is going to a point and runs through. here along the focal line at the inputs of the receiver. it is 30 cm 13 cm 6 cm 3 cm one and a half. 3 1/2 these dimensions, what they give is the wavelength of this radiation, the frequency corresponding to them, secondary mirrors are installed on cabins, each of which weighs at least 70 tons and moves along the rails per day, the irradiator, as it is called here, winds up to 70 km, making about a hundred permutations, the tool is so in demand by scientists around the world th
