US12516915 - Threat countermeasure system and threat countermeasure method

Provided are a threat-countering system and a threat-countering method for efficiently countering incoming threats by using laser irradiation. The threat-countering system comprises a countering device, a deterrent device, and a decision device. The countering device detects incoming threats and counters the threats by using laser irradiation. The deterrent device is installed to prevent threats from approaching a protected object through a deterrent region in which the power of the laser irradiation is assumed to be lower than a predetermined threshold. The decision device decides the position of the upper end of the deterrent device on the basis of the upper end of the deterrent region.

The patent describes a threat countermeasure system that utilizes laser irradiation to detect and neutralize incoming threats while incorporating a blocking device to prevent threats from approaching a protected target. Additionally, a decision device is included to determine the optimal positioning of the blocking device based on the defined threat zone.

Claim 1

1 . A threat countermeasure system comprising: a countermeasure device that detects an incoming threat and counters the threat with laser irradiation; a blocking device that is installed so as to block the approach of the threat to a protection target through a block region in which lethality of the laser irradiation is presumed to be lower than a predetermined threshold value; and a decision device that decides a position of an upper end of the blocking device based on an upper end of the block region. a countermeasure device that detects an incoming threat and counters the threat with laser irradiation; a blocking device that is installed so as to block the approach of the threat to a protection target through a block region in which lethality of the laser irradiation is presumed to be lower than a predetermined threshold value; and a decision device that decides a position of an upper end of the blocking device based on an upper end of the block region.
