METHOD OF AUTOMATIC ARMAMENTS HOMING AT MOVING TARGET Russian patent published in 2015 - IPC F41G3/00 

FIELD: weapon and ammunition.

SUBSTANCE: method of automatic armaments homing at moving target according to which the periodic image of the field of military operations is formed with a frame frequency, and after target detection, determination of its range, speed of movement and an altitude the lead angles of the weapon for the subsequent shot, differs by that, for the purpose of increase of probability of target destruction and safety of a shooter, after detection of the target the shooter by means of remote control moves the target image to such area of the field of vision of the optical-electronic system (OES) of the sight which would allow at stable position of the line of vision (LV) of OES to observe the target during the time sufficient for the first aiming operation; at this operation the position of LV OES is stabilised spatially; the marker is placed over the image of OES target; the sight operating mode is switched to automatic one at which OES marker moves together with the target, and OES at the beginning of each shot transfers the data (an azimuth and a angle of a place) of the target angular coordinates to the range finder; the range finder is automatically rotated towards the coordinates supplied by OES and as the target enters the sight of the range finder marker it sends an impulse of radiation and determined the range of the target which it transmits to the sight, providing the first triad of data (location angle, an azimuth and range of the target) which are saved in the sight memory; after the time Δt₀, multiple to the period of OES frame sweep, the range finder again measures the target range and again transfers the information on the target range to memory of the sight which automatically forms the second triad of data on the target position with reference to the sight; the calculator of the sight using both triads of data and the known time interval Δt₀, predicts the target position at the given moment T_P; and at calculation of T_P the following is taken into account: target speed; range and angle of the target altitude; time of shell flight taking into account the target altitude; dynamic parameters of the sight drive (time of rotation of the sight to the rated point); size of differential coordinates of the second and first triads of data; ambient temperature; wind direction and speed; then LV OES stabilisation is removed and the sight with the weapon stock is rotated towards the direction of the predicted position; after installation of the sight into the rated position at the given time T_P the shot is made automatically.

EFFECT: improvement of aiming accuracy taking into account parameters and target motion conditions, homing of the weapon to the rated direction with automatic providing the required lead angle, and the shot at the rated moment without participation of the shooter.
