摘要
Abstract
In naval warfare,infrared missiles are important weapons for destroying targets.To effectively demonstrate the ability of infrared missiles to destroy targets,it is necessary to first obtain the infrared target characteristics of typical destroyers.Therefore,this study investigated the infrared target characteristics of"Ali Burke"class destroyers.A three-dimensional physical model of the"Ali Burke"class destroyer was established.The flow field characteristics and medium-and long-wave infrared radiation characteristics of the model in the cruise state were calculated via numerical simulations.The results indicate that the plume temperature of the target chimney of the military ship is as high as 688.5 K,and the temperature of the ship body is low and uniform.The medium-wave spectral radiation of ship targets is primarily contributed by high-temperature plumes,whereas the long-wave spectral radiation is primarily contributed by the normal-temperature ship body.In addition,the characteristics of medium-and long-wave spectral radiation are significantly affected by the observation angle.The maximum value of the medium-wave spectral radiation intensity is 65000 W/(sr.μm),and the highest value of the long-wave spectral radiation intensity,18200 W/(sr.μm),is reached at the detection angle directly above.关键词
