Direct imaging methods, which are not based on nonlinear
optimization, have attracted a lot of attention recently. MUSIC
algorithm for a single frequency is capable of imaging in homogeneous
medium. We shall consider the imaging in random medium with multiple
frequencies. Numerical simulation for wave propagation in complex media
is a challenging multi-scale problem. We develop an approach to couple
parabolic approximation with full Helmholtz equation, and generalize the
Foldy-Lax formulation.
