摘要/Abstract

摘要： 在复合高斯杂波满足局部均匀的背景下，对均匀杂波分组模型进行推广，建立了广义杂波分组模型.进一步，利用广义似然比检验（GLRT）原理，提出了距离扩展目标的基于广义杂波分组的GLRT检测器（GCC-GLRT），并推导了检测器虚警概率与检测门限关系的表达式.GCC-GLRT有效地解决了基于均匀杂波分组的GLRT检测器（CC-GLRT）在非均匀杂波分组背景下不具备CFAR特性的问题.仿真结果还表明，对于稀疏散射点目标，在合适的杂波分组情况下，GCC-GLRT能有效克服采用NSDD-GLRT检测器出现的“坍塌损失”，改善检测器的检测性能.

关键词: 复合高斯杂波, 球不变随机向量, 杂波分组, 广义似然比检验

Abstract: When the compound-Gaussian clutters are cluttered into groups of data with one and the same value of the texture,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 relating 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.

Key words: compound-Gaussian clutter, spherically invariant random vector, clutter-clustered, generalized likelihood ratio test
