This paper focuses on using blind source separation of complex signals to extract scattering centers of radar targets that can then be used for target identification. The concept introduced in this paper assumes that the signal returned (or scattered) from a target is linear or convolutive mixture of several scattering centers along the body of an unknown aircraft. This information can then be used...
This paper addresses the problem of combining adaptive polarization processing and space-time processing for further performance improvement of radar target detection in clutter and jammer environments. Since the most straightforward cascade combinations have quite limited performance improvement potentials, we focus on the development of adaptive processing in the joint polarization-space-time domain...
The application of higher-order statistics (HOS) to velocity measurements of radar targets takes advantage of the HOS characteristic that fourth-order estimators can be unbiased by Gaussian noise. Using data from a stepped-frequency, coherent radar, the samples are coherently averaged in the trispectrum or in slices of the trispectrum. The ratio of the averages produces a transfer function where phase...
