ABSTRACT:
Systems and methods enable numerically creating a flat field in a compact radar range with a curved reflector, and without use of a separate phased array of elements, at frequencies lower than those that are possible with currently known, reflector-only compact radar ranges. A compact radar range is calibrated to enable weighting factors to be computed. The weighting factors may be computed by performing an optimization algorithm. The weighting factors are used to weight separate target signals sequentially returned from a target zone such that, when combined, a numerically composite measurement has a substantially constant magnitude across the target zone.
