METHOD OF AIMING OF GUIDED ROCKET Russian patent published in 2003 - IPC

FIELD: guidance of rockets based on land or mobile launchers. SUBSTANCE: second aiming line is formed simultaneously with first aiming line and is matched with target. Deviation of rocket from second aiming line is measured and second control instruction is formed in correspondence with its deviation from second aiming line. Signal to rocket controls is generated in compliance with sum of first and second instructions. Second aiming line is formed at acute angle with first aiming line which value is found from expression where l_min is minimal distance between shooting objects in plane parallel to pitching plane; D_max is maximum shooting range of guided rocket; γ- is acute angle between first and second aiming lines; D_min is minimal range of start of combined aiming of guided rocket (distance of crossing of boundaries of fields ( beams ) controlling rocket from shooting objects ); D_t is range to target; Ψ is divergence angle of field ( beam ) controlling aiming system of guided rocket which value is established by expression 10^°<Ψ<90^°. EFFECT: increased precision and speed of aiming, enhanced interference stability and immunity during aiming. 1 dwg
