Reconstruction of the scattering function of overspread radar targets

This study addresses the problem of stochastic radar target measurement. The authors develop an algorithm that allows for the reconstruction of the scattering function of a wide-sense stationarity with uncorrelated scattering radar target from the autocorrelation of the response of the target to a deterministic sounding signal. Although conventional methods are applicable only when the scattering function is supported on a `rectangle' with area <;1, the authors' method can handle area 1 support sets of `arbitrary' geometry. Based on the suggested theoretical recovery procedure, the authors propose an unbiased scattering function estimator
