【摘要】 为提高单脉冲雷达导引头对机载拖曳式诱饵的检测概率,文中研究了在诱饵释放干扰情况下单脉冲比的概率分布特性,以及基于奈曼-皮尔逊准则的复角检测方法。根据诱饵持续作用这一特点,在复角检测法基础上,提出了一种多次检测后判决的检测方法,并对新检测方法进行了理论分析。新方法充分利用观测信息,提高了检测性能。仿真结果表明,新检测方法能够有效降低虚警概率,提高发现概率。更多还原

【Abstract】 To improve mono-pulse radar seeker’s detecting probability for towed decoy,the probability density function and statistics of mono-pulse ratio,and the method of complex angle test based on Neyman-Pearson criterion were studied. According to sustained action of decoy,a new detecting method was put forward,which judges after several times of detection. Besides,theoretical analysis of new method was processed. By making full use of the received information,detecting probability can be improved. The results of the simulation show that the new method can provide higher detecting probability and lower false alarm rate.更多还原
