PROBLEM TO BE SOLVED: To provide an active defensive method against a missile capable of reducing explosive power of the missile, reducing a sensor function of the missile, or guiding the missile to a wrong vector by detecting the approaching missile. SOLUTION: Laser beams of pulses are received by a photoreceptor 46, and added to a gate 49 and a gate 51 as electric signals, the output voltage of the photoreceptor 46 is added to a counter 50 when it is over a threshold output of a threshold value setting unit 48 in the gate 49, and the gate 51 is opened when the number of pulses per a unit time reaches a prescribed number in the counter 50. When the gate 51 is opened, a distorted pulse train is reformed by a waveform shaping unit 52, and added to a laser diode 53, and the false laser beam is directly modulated and generated by the laser diode 53, amplified by an optical amplifier 54, and projected to a separated place from a projector of an automobile.
