Weak Signal Detection Technology Based on Phase-inversion Symmetric Method

摘要：

This paper introduces the principle of Phase-Inversion Symmetric Modulation (PISM) and its application in detecting weak signals. This paper also gives the simulation model and actual circuit diagram of PISM and attests its superiority in detecting weak signals from strong noise background. It has obvious effect in suppressing strong noise.
