A characteristic pattern of connections among neurons (nerve cell) in the eyes of most animals (including humans) is lateral inhibition network.

To solve the difficult detection problem of ship targets in low-resolution synthetic aperture radar(SAR) images for the reasons of the defect of the sea surface background and clutters,a background inhibition network modeling was built on the theory about the lateral inhibition mechanism of biology visions for the sea clutter and the speckle noise suppression.

In mathematics,Bubble function is always used to describe the lateral inhibition phenomenon of nerve system,and it can reflect the characters at time and frequency domains.
