A method of protecting a pulse radar from a missile attempting to home on interrogating pulses emitted by such radar, said method comprising the steps of providing a plurality of decoys at different locations in the vicinity of the pulse radar, each one of the decoys being adapted, when activated, to emit pulses of a given amplitude and duration; activating, when each one of the interrogating pulses is generated in the pulse radar, a selected decoy to lead the remaining decoys in the plurality of decoys for a period of time determined by range and range rate measurements of a pulse Doppler missile warning sensor, changing the decoy selected to lead the remaining decoys in the plurality of decoys at a time determined from range and range rate measurements of a pulse Doppler missile warning sensor thereby defining a blink rate associated with the decoys, to form a covering pulse overlapping the then emitted one of the interrogating pulses; and adaptively changing the blink rate and determining an associated maneuver change of said missile in response thereto, to obtain the blink rate that provides the maximum maneuver change associated with the missile.
