The shipboard optoelectronic countermeasure system is an important means again the photoelectric guided weapons.In order to improve the probability of success of laser-guided weapons against ships,the wake deviation indication method of laser guided attack on ships is studied.Combined with the characteristics of ship wake bubbles,laser semi-active guided mode,wake bubbles laser scattering model,a model of air-launched laser guided weapons for ship wake bubbles detection is established.The scattering characteristics of laser irradiated ship wake in different areas,different weather conditions and different irradiated angles are simulated.The research results can be used as a reference for new precision laser-guided weapon to attack ships with concealment.
