Scattering of Radar Waves by Mine Fields.
Abstract
Radar scattering by an array of surface land mines is studied. The array is considered to be a random perturbation of a uniform array. The analytical evaluation of the expectation is performed for this problem under specified, but realistic, assumptions. The analytic expression for the expectation contains coherent and incoherent array factors, each of which are summations of terms that areweighted by the effect of the antenna pattern. By curve fitting the antenna gain pattern with exponential functions in elevation and azimuth the resultant series are summable. The resultant expression for normalized signal to clutter ratio displays the coherent contributions from the radar system parameters (such as, beamwidths, frequencies, depression angle and pulse width) in conjunction with the randomness of mine placement and the clutter distribution.
