Target Detection in Compound-Gaussian Clutter with Adaptive OFDM Radar
This paper mainly deals with the problem of target detection in compound-Gaussian clutter with orthogonal frequency division multiplexing (OFDM) radar. First, the OFDM measurement model is developed to compound-Gaussian clutter by taking advantage of frequency diversity of OFDM radar waveform and we devise a generalized likelihood rate test (GLRT) detector where the target scattering coefficien...
متن کاملAdaptive Detection in Compound-gaussian Clutter with Inverse Gaussian Texture
This paper mainly deals with the problem of target detection in the presence of Compound-Gaussian (CG) clutter with the Inverse Gaussian (IG) texture and the unknown Power Spectral Density (PSD). The traditional CG distributions, in particular the K distribution and the complex multivariate t distribution, are widely used for modeling the real clutter data from the High-Resolution (HR) radars. ...
متن کاملRange-Spread Target Detection in Compound Gaussian Clutter with Reciprocal of the Square Root of Gamma Texture
In this paper, the range-spread target detection in compound Gaussian clutter with reciprocal of the square root of gamma (RSRG) texture is investigated. The RSRG distribution has been proved to be a good model for texture component of extremely heterogeneous radar clutter. Taking this compound Gaussian model as a spherically invariant random process (SIRP), the Neyman-Pearson optimal detector ...
متن کاملRadar Detection in Compound-gaussian Clutter
In this paper, we study the adaptive version of the asymptotical Bayesian Optimum Radar Detector (BORD) built with a covariance matrix estimate. We investigate its properties, when the noise is modelled as a non-Gaussian complex process, such as Spherically Invariant Random Process (SIRP). We derive, for appropriate covariance matrix estimates, the analytical expression of the relationship betw...
متن کاملAsymptotically Optimum Radar Detection in Compound-Gaussian Clutter
A substantial bulk of work is now available in the literature about detection in non-Gaussian noise. Starting with the experimental evidence that the Gaussian assumption is no longer met in many situations of practical interest, much effort has been directed towards the study of conventional detectors under non-Gaussian clutter as well as the design and the analysis of new optimized structures....
