Abstract

The level of noise is a critical figure of merit for acousto-optic processor (OEP). We introduce a simple model to calculation the variance of output response OEP with LFM input signal as a function of the parameters and operating mode of processor. In this paper are considered two operation modes of OEP, with digital and analog scanning. Acousto-optic processor for radio astronomy applications has been developed and of the experimental data is described. For the analysis of spatial-temporary signal wavelet transformation is used.
