RADAR Russian patent published in 1997 - IPC

FIELD: radars. SUBSTANCE: two matching circuit, two comparison circuits, distance code transducer, azimuth code transducer, fixed direction code transducer, two subtracters, decoder and air condition transducer are introduced to accomplish goal of invention. Output of distance transducer is connected to first inputs of first and second matching circuits, which second inputs are connected to outputs of first and second comparison circuits respectively. Second inputs of first and second comparison circuits are connected to output of azimuth code transducer and fixed direction code transducer. Outputs of first and second comparison circuits are connected to first inputs of first and second subtracters, which second inputs are connected to output of distance code transducer. Outputs of first and second subtracters are connected to first and second inputs of OR gate, which output is connected to air condition transducer through decoder. In addition first inputs of comparison units are connected to outputs of azimuth gage and fixed direction gage. EFFECT: detection of condition of air. 1 dwg
