METHOD OF CORRECTION OF SHOOTING FROM ARTILLERY-TYPE WEAPON Russian patent published in 2018 - IPC F41G3/00 F41G7/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to methods and means of artillery reconnaissance based on obtaining and analyzing photo images of the terrain with objects from the aiming area. Method for correcting firing from artillery guns is based on the preliminary determination of the parameters of firing with combat shells. According to these parameters, the gun is aimed and a cluster reconnaissance missile with ballistic characteristics identical to the service projectile is fired. With the help of a knockout device installed in the head of the projectile, clusters are thrown out of the shell of the projectile. Image of the terrain in the impact zone is photographed by one of the clusters. Image is transferred to the shooting unit. Based on the analysis of images, correction of the shooting is performed. Body of the reconnaissance shell is covered with a radio-absorbing coating. Clusters of the reconnaissance missile are made in the form of transceiver modules with in-flight stabilization devices. Modules are placed in the body of the projectile in series so that their stabilization devices are located on the side of the knockout device. First module (1) is left in the body of the shell after the knockout device is activated. Video information is formed about the position of the module (1) in the space before it falls onto the terrain. Second module (2) with the photodetector is oriented with the photodetector part in the module (1) falling direction. Series of consecutive digital photo images of the terrain is obtained. Marking is formed in the center of each image. Height of the module above the terrain is continuously measured. This information is transmitted to the third module (3). Third module is caused to fall at a rate of less than the speed of falling of the second module. It illuminates the terrain in the zone of falling of modules (1) and (2). Information is received from the second module and transmitted to the remote receiver. Information from the remote receiver is analyzed. On each frame of the terrain image, the height of the second module above the terrain, the position of the marking in the center of the frame, and the display of the marking corresponding to the position of the first module, are determined. According to information from several images, these markings are graphically tied to the terrain. Shooting direction is a line between these markings on different images. Point of detonation of a service projectile, when firing conventional ammunition, is the point of the position of the first module on the last frame of the terrain image. Distance from the marking in the center of the frame to the aiming point and other objects is determined by calculation.

EFFECT: it is possible to obtain photo information from a reconnaissance projectile, with the possibility of tying the graphic data obtained in this way to objects on the ground, and determine the direction of shooting and the point of detonation.
