POSITION CONTROL APPARATUS OF BEAM PATTERN OF ANTENNA OF MOBILE DETECTION RADAR Russian patent published in 2004 - IPC

FIELD: control and stabilization systems for measuring devices mounted on rocking base, possibly for controlling beams of antenna of two-coordinate mobile detection radar and following radar.

SUBSTANCE: control apparatus includes pickups for detecting lengthwise and crosswise inclination angle; units for setting elevation angle, azimuth; units for calculating sine and cosine of lengthwise and crosswise inclination angles, for setting azimuth, elevation angle of antenna; units for generating elevation angle of antenna and azimuth of sweep line; unit for displaying round surveillance and calculating azimuth, unit for displaying elevation angle, units for sampling and holding elevation angle and azimuth values; universal filter with amplitude and phase setter; drive units of elevation angle and azimuth whose outlets are connected with detection antenna, inlets of target azimuth signals, attribute of azimuth signal, target searching and target attribute signals; drive units for following according to elevation angle and azimuth whose outlets being outlets of the whole apparatus and designed for connecting with following antenna. Novelty is unit for forming inclination angle of cross lines, unit for calculating sine and cosine connected in series and combined with unit for sampling and holding inclination angle of cross lines; first and second multiplication units. Invention provides compensating correction, stabilizes position of symmetry plane of antenna beam pattern without data of target fluctuation relative to preset elevation angle, motion of beam pattern of following antenna along optimal path until time moment for coinciding it with target.

EFFECT: enhanced accuracy of generating target coordinates.
