In this communication we present a coherent interferometric (CINT) imaging algorithm to localize acoustic sources in random fluid flows. It uses empirical correlations of the acoustic waves recorded at the bottom of the flow to possibly locate the sources emitting the waves above it. We rely on an analytical model of wave transmission in randomly stratified fluid flows to develop the algorithm. This model is established in a particular regime of separation of scales.
