METHOD FOR INCREASING THE EFFICIENCY OF TARGET DETECTION UNDER THE INFLUENCE OF AEROSOL INTERFERENCE BY A NON-CONTACT TARGET SENSOR Russian patent published in 2023 - IPC F42C13/02 F41G7/22 

FIELD: military technology.

SUBSTANCE: invention can be used in non-contact target sensors (NCTS) of surface-to-air and air-to-air ammunition operating in the optical wavelength range. A method for increasing the efficiency of target detection under the influence of NCTS aerosol interference, including M≥2 transmit-receive channels, the signals in which are registered and recorded during the flight along the trajectory. The recorded data is analysed, an adapted response threshold of the NCTS - Sa is formed, the target is detected and a command is issued to detonate the warhead of the ammunition (warhead). For analysis, data obtained in the last i≥1 round views of the NCTS, with respect to the threshold Sa for each NCTS channel, additionally N≥1 thresholds with a level other than Sa are formed. Based on the results of each circular survey of the space, incoming signals are analysed at all levels, in all channels of the NCTS. When the level of the received signal exceeds the level of one or more additional thresholds in one or more channels, the NCTS analyses the number and location of the channels in which the excess is detected, and based on this information, a decision is made to detect a target, interference or a target located against the background of interference.

EFFECT: increase in the probability of target detection and a decrease in the probability of false alarms when operating in conditions of aerosol interference - meteorological formations due to faster adaptation of the threshold level to the current interference environment.
