IEEE汇刊AES 1998年7月号登载了“对K分布加高斯分布杂波的最佳和失配检测”一文。该文对雷达研究人员,特别对信号检测专业人员有参考意义。 大家知道,局部杂波功率的起伏是由雷达后向散射体的空间和时间变化所引起。这称为球面不变随机过程(Spherically Invariant Random Process—SIRP)。但是,我们感兴趣的工作情况是由地块和海区或云层和海区同时存在的后向散射。地、云的雷达回波可由高斯分布过程描述,而海回波遵循K分布随机过程。此外,热噪声总是存在于雷达接收机中,所以为了正确进
IEEE Journal AES July 1998 issue of “Best and Mismatched Detection of Gaussian Distribution Clutters for K Distribution.” This article has reference significance for radar researchers, especially for signal detection professionals. We all know that the fluctuation of local clutter power is caused by the space and time variation of the radar backscatter. This is called Spherically Invariant Random Process (SIRP). However, the work we are interested in is backscattering, which is co-existing with the area and the sea or the clouds and the sea. The radar echoes of clouds can be described by the Gaussian distribution process, while the sea echoes follow the K-distribution random process. In addition, thermal noise is always present in the radar receiver, so in order to go right
