Abstract

In IR detection, frequency modulation or time correlation is the important technique. In some signal detecting system, it is not enough of the technique. In this paper, multi- correlation of time and frequency is discussed, and the method of the technique is given. Time-position encoding technique is also discussed in the paper. When the new technique is applied in IR detecting system, the DC and adjacent radiation interference can be removed easily, and the system can work more reliably.
