RADAR FOR HELICOPTER Russian patent published in 2003 - IPC

FIELD: radiolocation. SUBSTANCE: technical result of invention consists in raised probability of detection of small-sized ground and surface objects against background of reflections from underlying surface due to increase of angular resolution and to enhanced operational efficiency of radar under complex meteorological conditions. This result is achieved by insertion into mix of radar equipment of array based on two-wire line made of film foiled dielectric with radiators in the form of printed vibrators which is placed in helicopter propeller blade in area of its maximal length. Mass of array used as antenna does not exceed 0.3 kg which markedly diminishes mass of radar equipment and its cost. EFFECT: raised probability of detection of small-sized ground and surface objects. 6 dwg
