    摘要:

    提出了将三重相关和重叠取样技术用于红外系统信号波形恢复的方法,研究表明,对低输入峰值信噪比用该方法可以用效地从噪声中恢复信号的波形,文中描述了在重叠取样的基础上进行三重相关操作的步骤,比较了“三重相关重叠取样法”和传统的“扫描取样积分法”的掏噪性能的优劣,给出计算机模拟实验的结果。

    Abstract:

    The approach of triple correlation overlapping sampling (TCOS) was presented for recovering signal waveforms of IR systems. Investigations show that signal waveforms can effectively be recovered in the low signal to noise ratio(SNR) circumstances using this approach. The restraining noise performances of triple correlation overlapping sampling and conventional scanning sampling integration were compared. The operations of TCOS were described and computer simulating experiment results were also given.
