I will introduce the concept that a strong source is also a good detector for signals of the same frequency. Base on this fact, and combine with other considerations, binary pulsars can be very good detectors for the stochastic gravitational waves background around 10^{-4} Hz. This frequency is relevant in constraining the white dwarf binary population in the galactic center, or preheating/phase transition at TeV scale. This method is fundamentally different from all existing GW detectors and has its unique advantage.
