A New Adaptive Linear Combined Cfar Detec- Tor in Presence of Interfering Targets
In this paper, a new radar constant false alarm rate detector to perform adaptive threshold target detection in presence of interfering targets is proposed. The proposed CFAR detector, referred to as Adaptive Linear Combined CFAR, ALC-CFAR, employs an adaptive composite approach based on the well-known cell averaging CFAR, CA-CFAR, and the ordered statistics, OS-CFAR, detectors. Data in the ref...
متن کاملDetection Loss Due to Interfering Targets in Ordered Statistics CFAR
0018-9251188/1100-0678 $1.00 (C 1988 IEEE Ordered statistics (OS) constant false alarm rate (CFAR) algorithm, introduced by Rohling [ I ] , is a CFAR technique with special immunity to interfering targets. CFAR usually suffers some detection loss due to the adaptive threshold concept. Furthermore, the presence of strong returns among the cells used to determine the background noise or clutter (...
متن کاملThe CFAR adaptive subspace detector is a scale-invariant GLRT
The constant false alarm rate (CFAR) matched subspace detector (CFAR MSD) is the uniformly most-powerful-invariant test and the generalized likelihood ratio test (GLRT) for detecting a target signal in noise whose covariance structure is known but whose level is unknown. Recently, the CFAR adaptive subspace detector (CFAR ASD), or adaptive coherence estimator (ACE), was proposed for detecting a...
متن کاملSystolic Architecture for Adaptive Censoring CFAR PI Detector
A new parallel algorithm for signal processing and a parallel systolic architecture of a robust constant false alarm rate (CFAR) processor with post-detection integration and adaptive censoring (RACPI) is presented in the paper. This detector is effective in conditions of flow from strong impulse interference. The ACPI CFAR processor uses sorting and censoring algorithms. We offer the sorting a...
متن کاملA New Class of Adaptive CFAR Methods for Nonhomogeneous Environments
The paper introduces a new class of adaptive CFAR methods to cope with the problem of outliers due to the presence of clutter edges and interfering targets. A fundamental distinction between the proposed approach and existing adaptive CFAR approaches is that in order to maintain robust performance the former uses information on positions at which estimated outlier-free cells appear in the full ...
