The present invention relates to a laser based system for protecting a platform against an armament equipped with an optical homing head element, that includes a command and control assembly equipped with an interface to a detection and acquisition system that detects and locates a threatening armament and receives from it a warning about the detection of said threatening armament combined with data relating to it; and a laser source operable by the command and control assembly in order to produce the required energy for jamming the optical head of the threatening armament; and wherein the system is characterized by that it includes in addition a sectarian array of a plurality of end units that are connected unto the laser source for selectively routing laser energy from the source to an end unit that was selected by the command and control assembly as the end unit that is best suited under prevailing conditions for pointing at the threatening armament and attacking it by emitting a laser beam in its direction.

Laser based countermeasures system and method

An interceptor fitted with a target tracker unit, that includes passive infrared tracker capable of sensing infrared radiation (IR) emitted from a flying target and being responsive to the sensed IR radiation, for generating a succession of Line of Sight (LOS) and/or LOS rates signals that are stored in a database. Self state means capable of providing a succession of interceptor's self state data. Electro-magnetic range finder that includes a transmitter assembly for transmitting pulsed radiations and receiver assembly for receiving reflections that surpasses adjustable detection threshold. The electro-magnetic finder is configured to operate at first detection threshold for receiving reflections of relatively low magnitude, and storing the reflections in the database. A target reflection detection module communicating with the database, for detecting target reflections from among those stored in the reflection database. Estimator that includes range-based target estimator for calculating target state estimations on the basis of detected target reflections, the LOS measurements and self stage data, thereby facilitating early steering of the interceptor for duly homing said interceptor onto the target.
