Comparison of the conventional statistic
and new coherence methods for the weak signal detection in the case of
high background is made. We have established that for low signal-to-noise
ratios the coherence location methods are more sensitive than usual
ones. New technologies of the coherence signal treatment actually raise
the sensitivity of signal detection by more than 20 dB.
