ABSTRACT:
A computer implemented method and system for preparing a description of an electromagnetic scattering net approximating an actual scattering net for analyzing effect on sensor imagery is comprised of: (1) inputting a basic tent configuration comprising a number of tent poles, spacing of tent poles, a covering net, an amount of net sag, and plurality of locations of ground anchor points, representing the design variables selected by an operator from which a net can be modeled; (2) dividing the overall net shape into a plurality of large facets that describe the overall shape conforming to the basic net configuration; (3) subdividing each large facet into a plurality of small facets in accordance with the input number of small facets per large facets chosen so that the small facets correspond in wavelength to the scattering of an actual scattering net; (5) rotating each small facet to achieve an approximation of the signature reduction of an actual scattering net; and (6) outputting a description of rotated small facets. The invention supports the application of CAD and sensor/seeker simulation methods and tools to the evaluation of the effectiveness of a variety of radar scattering net design and employment practices. It supports the capability to produce radar imagery or signal predictions which include the effects of radar scattering net treatment. The resulting predicted imagery or signals may be used to support mission planning and rehearsal, imagery analyst training, weapon system operator training, weapon seeker algorithm development, and automatic target cueing and recognition algorithm development.
