GUIDANCE SYSTEM OF TELECONTROLLED MISSILE Russian patent published in 2002 - IPC

FIELD: rocketry, applicable in armament complexes of telecontrolled missiles. SUBSTANCE: the guidance system has a target direction finder, first and second differentiating-ripple filters and a missile pitch and heading control circuit, including a unit for formation of the dynamic error compensation signal, introduced are a coordinate converter from the spherical coordinate system to the rectangular one, coordinate converter from the rectangular coordinate system to the spherical one, the third differentiating-ripple filter, first, second and third units for formation of linear coordinate signals, target speed and acceleration, each having a line filter with an adjustable bandwidth, first, second, third fourth, fifth and sixth coefficient units, first, second and third inertial links, series-connected module separation unit, threshold device and a controllable multiplexer. Its second, third, fourth, fifth, sixth and seventh inputs are connected respectively to the outputs of the first, second, third, fourth, fifth and sixth coefficient units, the first, second and third outputs of the controllable multiplexer are connected respectively via the first, second and third inertial links to the second, third and fourth inputs of the line filter with an adjustable bandwidth. The first, second and third inputs of the coordinate converter from the spherical system to the rectangular one are connected respectively to the first, second and third outputs of the target direction finder, the first and second outputs of the coordinate converter from the rectangular coordinate system to the spherical one are connected n the respective control channel respectively to the first and second units for formation of the dynamic error compensation signal. The first inputs of the line filters with an adjustable bandwidth are connected respectively to the first, second and third outputs of the coordinate converter from the spherical coordinate system to the rectangular one, and their first, second and third outputs are connected respectively to the first, second and third inputs of the respective channel of the coordinate converter from the rectangular coordinate system to the spherical one, the inputs of the differentiating-ripple filters are connected respectively to the first inputs of the line filters with an adjustable bandwidth, and the outputs are connected respectively to the inputs of the module separation unit respectively of the first, second and third units for formation of signals of linear coordinates, speed and acceleration. EFFECT: enhanced accuracy of guidance. 1 dwg
