Abstract

Gravitational Wave (GW) detection is an important and inspiring project. Once detected, it will open a new window to understand the universe. The laser interferometer GW detectors, specially LIGO, is the most sensitive detectors at the moment, which can detect GW signal as weak as 10−21. Chirp signal generated by neutron star binaries is a well modeled waveform. One goal of LIGO is to study chirp signal detection. In this field, matched filtering is a widely used method. But since LIGO noise is non-stationary, which will weaken the efficiency of general matched filtering. In this work, a modified matched filtering is built to take non-stationary into account.
