Active protection method and system

Abstract

There is provided an active protection system and an active protection method preferably for airborne platforms. According to the embodiment of the invention, the active protection system is mounted onboard a platform for protecting the platform, and comprises a radar system configured for generating output data including threat output data corresponding to a velocity, a range, and an angle of the threat with respect to the platform in an airspace around the platform, the output data being useful for detecting, identifying and tracking of at least one threat approaching the platform; a countermeasure system capable of launching at least one non-fragmentation interceptor projectile in response to receiving a control command; and a control unit configured for receiving the output data from the radar system and for generating the control command and transmitting the control command to the at least one non-fragmentation interceptor projectile, thereby enabling countering the threat.

Description

FIELD OF THE INVENTION[0001]This invention relates to an active protection method and system and more specifically to active protection method and system for providing protection from a threat, particularly for use with a mobile or aerial platform such as a helicopter, UAV (Unmanned Aerial Vehicle) or the like.BACKGROUND OF THE INVENTION[0002]A variety of methods are known relating to protecting a vehicle or the like from a destructive threat.[0003]For example, U.S. Pat. No. 4,233,605 discloses a Doppler radar signature simulator decoy for protecting a helicopter under attack by hostile weapons which home in on a Doppler radar return signal from the helicopter rotors. The decoy returns a strong radar signal which duplicates a relatively weaker signal emitted from the helicopter rotors, leading hostile weapons to the decoy.[0004]U.S. Pat. No. 6,980,151 discloses a bi-static continuous wave radar system and related methods for detecting incoming threats from ballistic projectiles incl...

AI Technical Summary

Benefits of technology

[0034](c) based on at least the output data, generating the control command and transmitting the control command to the at least one non-fragmentation interceptor projectile,thereby enabling countering the threat.

Problems solved by technology

The decoy returns a strong radar signal which duplicates a relatively weaker signal emitted from the helicopter rotors, leading hostile weapons to the decoy.

RPG's (Rocket Propelled Grenade) represent a serious threat to mobile land and aerial platforms.
