Claim:
1. A method comprising the steps of: determining a grid using an acoustic model to compute replicas that correspond to simulated acoustic sources at locations in collecting, using the acoustic sensor array, time series data of actual acoustic measurements at each sensor of the acoustic sensor array caused by the acoustic sources; using a discrete-time Fourier transform (DFT) on the collected time series data to compute Fourier coefficients at frequencies {ω constructing DFT coefficient vectors y modeling DFT coefficient vectors at ω obtaining, at time t, an estimate Ŝ(t) according to the equation where S:=[s 1 , . . . , s F ], g ′ is the g-th row of S, P f :=[p 1,f , . . . , p G,f ]ε N×G is the matrix of replicas for ω f , and μ, λ>0 are tuning parameters; and constructing one or more source location maps (SLMs) over
