Optimal sensitivity for unequal arm time-delay interferometry
A new algorithm can obtain optimal sensitivity curves directly,without relying on time-delay interferometry configuration orthogonalization process.When applied to both first-and second-generation time-delay interferometry,the sensitivity curves remain robust under various arm lengths and baseline configurations.When the base number is increased from 3 to 5,the sensitivity curve is significantly optimized.With only three bases and within the frequency range of 0.001 to 0.100 Hz,the selection of specific bases affects the performance of optimal sensitivity curve.
