Application of Microwave Remote Sensing in the Detection of Buried Objects

Abstract

The detection of buried objects by electromagnetic waves have been carried out by using active microwave remote sensor at 9.50 GHz. We have taken various objects to accommodate various degree of contrast level as far as the dielectrics and conductivities are concerned with the surrounding medium taken as sand in the present study. Measurements were performed with the help of monostatic active microwave scatterometer. Scattering measurements of buried objects were done along the x- and y-axis assuming xy-plane parallel to the surface of the earth. Calculations have been done for the values of relative amplitude from the knowledge of the back-scattered and incident signals. The original and the observed sizes and shapes of objects have been shown for comparison. The results are very encouraging as far as the detected shapes are concerned as they have been found very close to the actual objects. The role of such detection in designing microwave remote sensors as a payload for future remote sensing satellites are outlined.
