Abstract—Aiming at ship-borne laser weapon damage to anti-ship missile, laser soft damage to IR seeker was researched. First, link model on laser disturbance to antiship missile IR detector was set up. Laser atmospheric transmittance on the sea was deduced. 1.06μm laser atmospheric transmittance on the sea was calculated. The relationship was obtained among atmospheric transmittance and visibility and elevation. Then 10.6μm laser atmospheric transmittance curve was described. The curve is changed by visibility and propagation distance. And then the experiment on laser disturbing CCD imaging system was accomplished. Pixel saturation threshold was measured. CCD saturation power density threshold was also measured. The curve was described. The curve is changed by laser incident energy and CCD saturation area ratio. Saturated area is increasing rapidly with the laser energy increasing; when laser energy is low. Saturated area is increasing slowly with the laser energy increasing; when laser energy is large. Finally, 1.06μm laser was given as an example, the necessary laser energy which can disturb effectively anti-ship missile IR detector was calculated. Some valuable data and conclusions were gained.
