Scale-Invariant GLRT in Stochastic Partially Homogeneous Environments
The generalized likelihood ratio test (GLRT) for a stochastic partially homogeneous model is proposed for adaptive signal detection. The stochastic partially homogeneous model generalizes the standard partially homogeneous model by treating the disturbance covariance matrix as a random matrix. Specifically, it assumes that, R, the disturbance covariance matrix of training signals, is a random m...
متن کاملA combined stochastic/decision-aided SNR estimator
A problem of a blind stochastic SNR estimator and a principle of SNR estimation combining a blind estimator and decision-aided estimator are presented. Signal and noise can be detected from the received signal by a decision depending on a decision threshold that is made available by using the second and fourth-order moments of the received signal. Subsequently, the SNR is computed from the dete...
متن کاملParametric Rao test for multichannel adaptive detection of range-spread target in partially homogeneous environments
In this paper we deal with the problem of detecting a multi-channel signal of rangespread target in the presence of Gaussian disturbance with an unknown covariance matrix. In particular, we consider the so-called partially homogeneous environment, where the disturbances in both the cells under test (primary data) and the training samples (secondary data) share the same covariance matrix up to a...
متن کاملAdaptive polarimetric detection method for target in partially homogeneous background
In this paper, the problem of enhancing the detection performance of detector for target in partially homogeneous background is addressed. Based on a general measurement model, a new constant false alarm rate (CFAR) adaptive matched detector (AMD) is proposed through a two-step design procedure. The detection performance of the AMD is theoretically analyzed. Then, the correctness of the analyti...
متن کاملStochastic Decision Making in Manufacturing Environments
Decision making plays an important role in economics, psychology, philosophy, mathematics, statistics and many other fields. In each field, decision making consists of identifying the values, uncertainties and other issues that define the decision. In any field, the nature of the decisions is affected by environmental characteristics. In this paper, we are considered the production planning pro...
