摘要
讨论了球不变随机过程（ＳＩＲＰ）非高斯杂波背景下高分辨雷达距离扩展目标检测问题。文中提出了ＣＡ－ＣＦＡＲ，ＯＳ－ＣＦＡＲ两种距离扩展目标检测器，并证明了它们的形状因子和尺度因子未知的情形下具有恒虚警性，即双参数恒虚警性，分析了这两种检测器的检测性能。这两种检测器亦可用作ＳＩＲＰ杂波背景下低分辨雷达检测器。
For high resolution radar, the echoes of target come from several points rather than one point as in low resolution radar. In this case the target is called an extended target. This paper presents two CFAR detectors for such a target in non Gaussian clutter, which are CA CFAR and OS CFAR detectors. The detection performances of the two detectors are evaluated.
