Non-Contact Detection Techniques And Technologies For Detection Of Objects In Air, Under-Ground And Under-Water, Raman Attri

In this white paper, we will present review and compilation of various object detection techniques currently available in different scenarios and situations. Automatic Object detection in the air, beneath other materials, under water and under the earth surface as well as over the surface is one of the advanced sciences employing many principles of multiple engineering domains together. “See-through” methods – seeing beyond the visible objects, has been inherent desire of human being since the practice of science. Not only this, a craving to detect the objects without directly “seeing upon” them with naked eyes calls upon some automatic procedures …

In theory, matched field processing offers the significant benefit of higher signal gains and increased localization capability. However, this has not been robustly observed in practice because of inherent uncertainties about details of the shallow water propagation environments which limit the prediction of the channel response. The use of guide sources to directly measure the transfer function between source and receiver arrays has been proposed as a means for reducing mismatch. However, the guide source measurement only provides a measured transfer function at the guide source location. In this paper a method of depth-shifting guide source observations is proposed, making …
