SOLUTION OF THE PROBLEM OF PROVIDING THE MINIMUM DETECTIVITY OF VARIOUS OBJECTS AT A SHALLOW DEPTH OF WATER BODIES
The problem of placement of objects at the bottom of shallow water bodies, imperceptible for a laser bathymetric detector, is formulated and solved. It is assumed that the bathymetric detector is installed on the aircraft. A mean-integral model of bathymetric detection of bottom objects using a beam of a laser source for reflection from an object is considered. It is shown that the average integral value of the relative value of the signal reflected from bottom objects will have a minimum when providing the inverse logarithmic dependence of the height of the detected objects on the ratio of the reflection coefficients of the object and the bottom. Such a minimum reflected signal guarantees a minimum probability of detecting objects placed on the bottom.
