Exploring the constituents of dark matter (DM) and how it interacts with regular matter has resulted in a multitude of theories and detection strategies requiring further exploration. For ultralight dark matter, which behaves like a wave, each detector can read the same signal, but its measurement will be affected by the phase shift of the DM signal, which can be calculated using the distance between each detector. This study focuses on the spatial correlation analysis of the DM signal obtained from multiple sensors. To show this correlation, I created a program that models the DM signal at multiple locations on Earth while accounting for the orbit and rotation of the Earth. In addition, the data will include both the desired signal and noise from various, typically uncorrelated, sources. By utilizing the spatial correlation between detectors, we can enhance the confidence of signal detection due to improvement in signal-to-noise ratio.
