In nonmechanical beam steering with phase conjugate (PC) mirrors, the scattered and reflected beams from a foam target are utilized. A scattering and reflection model has been made that coincides with the experimental results with an error between ±15%. In the case where four probe beams irradiated a foam target, the three-dimensional intensity distribution was simulated. The peak-to-minimum variation of the reflected plus the scattered energy per unit solid angle was [approximately]20% of the average energy.The PC beam direction needs to compensate for target motion (v [approximately] 300 m/s) to accurately irradiate an injected target with laser beams in the method of beam steering with PC mirrors. The compensation with four-wave mixing utilized as a PC mirror is shown. A PC beam can be adjusted by properly setting the angle between two pump beams.
