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.
