First,the original image is decomposed with wavelet,ratio edge detector is adopted to get the edge direction of manmade targets and Frost filter is performed in the direction,thus efficiently restraining cloud noise and strengthening the manmade target and its edge information at the same time.

The infrared extinction performance of carbon nanofibers used as smoke interference materials was studied within a smoke chamber.

According to the attacking azimuth of laser guided missiles and the weather condition of operational waters,how to confirm the launching scheme of smoke rocket and the scheme of the ship s evasion is the key problem needed to be solved when taking the tactical method of smoke jamming to defense against enemy s laser guided missile.

Three factors involved in smoke jamming are modeled and simulated.

The smoke jamming can make the electro-optical guidance missiles off-course,reduce the hit probability and protect the ship.
