Abstract :
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.
