m and σ are the mean and standard deviation of the noise,respectively; Subscript 0 and n mean original and compressed noise; $N t$ and $N r$ are the theoretical and real number of echoes greater than $m 0 + σ 0$ in the filter box; The dashed boxes in the right side indicates the detailed steps of noise compression in the left side
