摘要
反舰导弹末制导雷达在进行自动跟踪前,首先要在方位向和距离向上对目标搜索并进行检测。末制导雷达的检测性能与脉冲积累数目、信杂比和搜索方式密切相关。针对反舰导弹末制导雷达常用的扇形搜索方式,提出一种二项式积累OS-CFAR检测算法。该方法在一个方位搜索周期内对距离向回波进行非相参积累。仿真分析表明,与常规OS-CFAR算法相比,该检测算法提高了末制导雷达的检测性能。
Before automatic tracking, the anti-ship missile terminal-guidance radar searches and detects the designated vessel targets in both bearing and range. The number of pulses accumulated, Signal to Clutter ratio （SCR）, as well as the searching mode directly determine detection performance of the seeker. This article, by presuming the representative scenario and supposing in reason, proposes a method of binomial accumulation OS-CFAR（Order Statistics-Constant False Alarm Rate） detection algorithm in the presence of sector-region searching mode by accumulating irrelevantly the radar echoes in every dwell interval. The simulation result demonstrates the enhanced detection performance of this novel approach, compared to the ordinary OS-CFAR method.
