The scattered wave seismic method is now well appreciated and developed with the advancement of technology and requirement of seismic survey. Particularly in high-precision prospecting of complicated structure area, it has broad application prospect. Different current numerical modeling of scattered wave has their advantages and disadvantages. This paper has designed a method of Integration in FK domain based on perturbation theory to solve scattered field, which could obtain scattered field by integration in FK domain after get the total wave field. It has improved the data source of scattered field and the processing of space energy. The computational accuracy and efficiency of scattered field have got better. In addition, based on the algorithm a forward modeling test is carried out for the dynamics of scattered field. The features of kinetics of scattered wave amplitude are analyzed quantitatively from the perspectives of space distribution of perturbing body and disturbance quantity. Based on this, it obtains five experiential constants and provides the corresponding formula and physical significance. Scattered wave could be classified into different dynamical characteristics by the constants.
