Signal to noise ratio at the output of a linear system of signal processing of a linear antenna array

The signal to noise ratio is theoretically considered at the output of a multichannel acoustooptical processing system using the photoreceiver with signal accumulation (device with charge bond). The expression obtained allows one to calculate sensitivity and other characteristics. Noise distribution is assumed to be normal because the accumulation time essentially exceeds the noise correlation interval. To take into account the influence of internal photoreceiver noise and following devices one needs to add this noise variance to variance of noise caused by input noise.
