Description
The circular polarized astrophysical gravitational wave backgrounds may exist with detectable SNR for a finite observation time and the sensitivity of detectors, and may become the foreground radiation for observing the circular polarized cosmological gravitational wave background.
In this work, we developed a new analysis method introducing Stokes parameters into the gravitational wave radiometry to search for scattered background gravitational wave sources assuming circular polarized astrophysical gravitational wave backgrounds. We have also tested this method by analyzing simulated data of gravitational wave signals arriving from typical directions. In that analysis, it was confirmed that the modification of the radiometry filter function by the introduction of Stokes parameters can distinguish the polarization to observe gravitational waves.
