PASSIVE RADAR CAMOUFLAGE Russian patent published in 1995 - IPC

FIELD: passive camouflage against radar reconnaissance and weapon guidance systems, in particular, in camouflage curtains of radar-reflective dipoles. SUBSTANCE: enhanced efficiency of dipole curtains is attained by imparting the radio-absorbing capability to them and increasing the time of effective action at simultaneous perfection of service characteristics, the increase of mechanical strength, elasticity, elimination of adhesion properties, etc. inclusive. Radio-reflective dipoles are completely made of current- conducting material, doped polymer is used for the purpose. At putting of radio-absorbing curtains at maximum countermeasure range use is made of radar-reflective dipoles extended in the direction of maximum electrical conduction of doped polymer. For their manufacture use is made of ferromagnetic polyacetylene magnetized to saturation, p-doped by iodine or n-doped by sodium. Radar-reflective dipoles are made as strips or bands of various length from doped polyacetylene or as sections of fibre from doped polythiophene. EFFECT: enhanced efficiency. 6 cl, 2 dwg
