| 摘 要： | 研究了A/CFruit强干扰环境下S模式前导脉冲增强检测技术。分析了前导脉冲检测的依据和作用,将前导脉冲检测分为初检、有效性确认和参考电平产生3个步骤。在初检中采用前沿检测法和脉冲匹配检测法获得脉冲位置,对脉冲位置作位置匹配以初步确认前导脉冲的出现,用S模式数据位特有的脉位调制进行有效性确认,统计4个子脉冲在2dB内电平最多的点作为参考电平输出。仿真实验验证了算法的有效性。

| Abstract: | Enhanced techniques to declare Mode S preamble pulses in high Mode A/C fruits environment are discussed in this paper. Basis and roles to detected preamble are analyzed first. The improved preamble detection algorithm includes three steps:preamble detection,preamble validation,and reference level generation. Leading edge detection method and pulse matching method are employed to acquire pulse positions,then detect preamble by position matching. The PPM encoding used in the data block is difficult to generat... |
