Abstract
An approach to the search and detection problem of noise-like signals, based on the automatic adaptation of the duration of the coherent–integration segment to the communication channel frequency instability level, is proposed. As a parameter indirectly characterizing the frequency instability level, the estimate of the ratio between the powers of the signal–noise mixture at the output of the coherent–incoherent integrator measured at the minimum and maximum durations of the coherent-integration segment is used. The operability and efficiency of the method have been supported by the comparative simulation results.
