Method for detecting fire, explosion, and/or projectile penetration.

摘要

A method of detecting the occurrence of a fire or an explosion in a monitored space, or the penetration of a projectile through a barrier, by: transmitting to the monitored space an electromagnetic signal of at least one radio frequency; receiving the transmitted signal as scattered by the monitored space; and analyzing at least one parameter of the received signal to produce an indication whether a fire or explosion has occurred, or a projectile has penetrated through a barrier, in the monitored space.
