Tumble-average radar backscatter of some thin-wire chaff elements

With sinusoidal bases and Galerkin's method, the tumble-average radar backscatter is computed for parallel wires, crossed wires, a planar tripod, and a regular quadripod. This communicalion presents calculated and measured results. One of the configurations, the quadripod, demonstrates attractive tumble-average properties for use as a chaff element.
