Adaptive Detection of Spread Targets in Nonhomogeneous Environments: A Bayesian Approach

Abstract: the problem of adaptive detection of spatially distributed targets or targets embedded in no homogeneous clutter with unknown covariance matrix is studied. At first, assume the clutter is complex circular zero-mean Gaussian clutter with an unknown positive definite covariance matrix, and it is independent of the covariance matrix vector under test; the secondary data are assumed to be random, then the properties of complex Wishart distributed is researched. Next, the Generalized Likelihood Ratio Test (GLRT) de… Show more

“…In general, infrared small target detection methods can be classified into two categories: single frame and sequential detection. Sequential detection methods, such as the interframe difference method [7], optical flow method [8], [9], three-dimensional directional filtering [10], and Bayesian theory [11], perform well when the target has prior knowledge of the shape and position in adjacent frames. However, obtaining prior knowledge in practical military applications is extremely difficult.…”
