In this letter, we consider the problem of constant false alarm rate (CFAR) detection in heterogeneous scenarios. We assume that the covariance matrices of the training samples are different from that of the cell under test and employ prior statistical knowledge to describe the degree of heterogeneity. We derive an approximate expression of the average signal-to-clutter-noise ratio loss of the adaptive...
The paper presents the average signal-to-clutter loss (SCRL) analysis for polarimetric space-time adaptive processing by exploiting the Kronecker structure of the clutter covariance matrix (CM). An expression for the average SCRL as a function of the mean square error of the corresponding CM estimator is derived. Based on that expression, one can determine how many samples are required in order to...
Space-time adaptive processing (STAP) is widely applied in airborne planar array phased radar to suppress clutter or interference, especially range ambiguous clutter. This approach requires an accurate estimation of clutter covariance matrix(CCM) by the secondary data snapshots. However, in the forward-looking scenario angle-Doppler relationship is severely range-dependent(i.e clutter nonstationarity),...
