Gravitational lensing of core-collapse supernova gravitational wave signals

We discuss the prospects of gravitational lensing waves (GWs) coming from core-collapse supernovae (CCSN). As CCSN GW signal can only be detected within our own Galaxy and local group by current upcoming ground-based detectors, we focus on microlensing. introduce a new technique based analysis power spectrum association peaks with amplification factor to identify lensed signals. validate method applying it CCSN-like mock signals point mass lens. find that unlensed differentiated using more than one sigma for lens masses M$_{\rm L} {>} 150{\rm M}_{\odot}$. also study correlation integral between spectra corresponding factor. This statistical approach is able differentiate lenses as small {\sim} 15{\rm Further, demonstrate this used estimate in case lensed. The general applied any broad band especially useful incoherent
