The study of the computing optic scatterring of a complex target is presented. A self adapting integral step arithmetic is obtained. By this method, the optic scatterring of an aerial target with coating material is developed, and the calculation results under pulse and continue wave irradiations are given. A comparison of this method with the constant step method shows that the calculation speed is increased by five times with the same calculating precision.
