Experimental data was obtained using the Doppler log installed on the boat tacks – North water area of Ladoga lake at depths greater than 100 m. The Gain at the gate of the synchronous receive 4 channels was constant, the ratio s/n >> 1. The obtained coefficients of variation, temporal and spatial correlation. Estimates are compared to traffic conditions with a small velocity and stop the boat. Examines the relationship of ratings with the top layer of the bottom, having in some seas.
