Numerical Parametric Study of Electromagnetic Wave Scattering by Buried Dielectric Land Mines
Abstract
The unimoment method is applied to solve the electromagnetic scattering by a buried dielectric finite cylinder simulating a land mine. Computed results are reported at frequencies from 400 MHz to 1400 MHz at 100 MHz intervals. The dielectric constants of the ground are considered to be dispersive which simulates soil with 5%, 10% and 20% water content. Results are computed for the scattered electric and magnetic fields which are presented in terms of the cylindrical components of E and noH at a distance of 1 in. to 4 in. above the ground at 1 in. intervals. The numerical results are computed along the positive x-axis for each azimuthal mode. The fields at points on the positive x-axis may be obtained by summing the modal fields directly. Fields at points other than the positive x-axis may be obtained by summing the modal fields multiplied by the proper azimuthal function. Sample results are given in the report and the complete data are stored on magnetic tape. This report include documentation for the tapes.
