APPROACH OF TRIPLE CORRELATION OVERLAPPING SAMPLING FOR SIGNAL RECOVERY IN IR SYSTEMS
红外系统信号恢复的三重相关重叠取样方法

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.
