Abstract

The paper is devoted to effectiveness of determination of code patterns of phase-keyed signals in an acoustooptical demodulator at reception of the phase-keyed signals in the presence of intrinsic and external clutter. It is assumed that the duration of constituent pulses of the phase-keyed signal is commensurable with dimensions of the aperture of the ultrasonic modulator of light. Analysis of probabilities of detection of presence and absence of signal phase jumps is included.
