局部均匀背景中距离扩展目标的GLRT 检测器及性能分析
GLRT Detector of Range-Spread Target in Local Homogeneous Background and Its Performance Analysi s
摘要
Abstract
When the compound-Gaussian clutters are cluttered into groups of data with one and the same value of the tex-ture ,the homogeneous clutter-clustered model is generalized ,and a generalized clutter clustered model is established .Moreover ,a generalized likelihood ratio test detector based on the generalized clutter-clustered (GCC-GLRT ) is proposed ,and the formula relat-ing false alarm probability to detection threshold is deduced .The GCC-GLRT solves the problem that the CC-GLRT is not CFAR in inhomogeneous clutter-clustered background .The simulation results show that the GCC-GLRT can overcome the collapsing loss of the NSDD-GLRT detecting spare scatterers target and improve the detection performance of the detector .关键词
