METHOD FOR LAUNCHING A SURFACE-TO-AIR MISSILE AND SURFACE-TO-AIR MISSILE LAUNCH SYSTEM Russian patent published in 2023 - IPC G01S13/02 F41H11/00 

FIELD: rocket engineering.

SUBSTANCE: invention relates to aviation technology and can be used in facilities equipped with radio location information means for detecting, tracking targets and direction-finding missiles. To realise the technical result, the target is detected and tracked while measuring the coordinates and radial velocity thereof; the type of target and the energy level of the signal reflected from the target are determined, determining the signal-to-noise ratio (S/N) in accordance with said level; launch zones are defined depending on the characteristics of the SAM; the SAM is launched and aimed at the tracked target. After the target detected and tracked, the S/N ratio of the signal reflected from the target is smoothed, the point of collision of the SAM with the target is calculated based on the current coordinates of the target, and the predicted value of the S/N ratio at the time of collision of the SAM with the target is determined based on the required precision. At the same time, the required value of the S/N ratio is determined at the point of collision of the missile with the target, followed by comparing the required level of the S/N ratio with the predicted level at the time of collision of the missile with the target, and if the predicted level exceeds the required level, a launch permission signal is issued; is the target is located within the launch zone and the missile is ready for launch, it is launched and aimed; if the predicted value of the S/N ratio is less than the required value, and in cases of modulation in the signal reflected from the target, a confidence interval of permissible values of the required S/N ratio is generated, depending on the characteristics of the radar and the target, and if the values of the predicted S/N ratio are within this confidence interval, the missile is fired.

EFFECT: higher precision of launching surface-to-air missiles (SAMs).
