Detection 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 کاملSensitivity of API CFAR Detectors Towards Change
In this paper, we estimate the sensitivity of the adaptive censoring algorithm towards the change of the input parameters of pulse jamming of an Adaptive Postdetection Integration (API) CFAR processor. The censoring algorithm estimates the background environment and automatically defines the scale factor. We propose this algorithm to be used for the estimation of both, the probability of appear...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Performance Analysis of Generalized Modified Order Statistics Cfar Detectors
Generalized Order Statistic Cell Averaging (GOSCA), Generalized Order Statistic Greatest Of (GOSGO), and Generalized Order Statistic Smallest Of (GOSSO) CFAR detectors are proposed. Each of them has its own advantages according to radar environment situations so that most effective radar detector can be chosen at any unpredictive situation. Their performance formulas in terms of false alarm pro...
متن کاملCFAR detectors for hybrid-search acquisition of Galileo signals
The acquisition of code phase and frequency shift is a pre-requisite for any Code Division Multiple Access (CDMA) system. One important step in the acquisition process is the choice of a suitable decision variable and of an appropriate threshold, which will determine the probabilities of detection and false alarm. In serial-search strategies and in many hybrid-search strategies proposed in lite...
