Abstract:
The algorithm for reconstruction of a signal is proposed to be employed in the space information-measuring system (SIMS) for detection and ranging of a source of pulsed optical radiation from space through a cloud layer. The analytical model of a path of signal propagation through the atmosphere with a cloud layer is used for deconvolution of signals. A modification of the well known mathematical apparatus, without changing characteristics of the model, as applied to direct problems, allows solution of the inverse problem, namely, determination of the values of the path's parameters from SIMS data and, finally, deconvolution of the signal transmitted by a source. Computations are made automatically with a digital processor equipped with a fast transversal filter in the additive operating mode.
