Active, broad-band phased arrays can be used for remote sensing in a randomly inhomogeneous environment where there is a lot of multiple scattering (multipathing). I will explain in detail why this is so and what signal processing methods one has to use not only to neutralize noisy medium effects but, in some cases, to take advantage of them with time-reversal techniques.
