Description
This project aims to investigate optimal observational modes of radio interferometric arrays for diverse scientific goals (e.g., PTAs) using numerical simulation tools.
We develop an open-source software framework capable of generating simulated pulsar timing data and injecting multiple signals, including gravitational waves. Leveraging existing observational datasets, we use this framework to analyze how to rationally configure observational parameters—such as observing time, number of subarrays, and observing frequencies—for specific scientific objectives, thereby identifying optimal observing strategies.
The results will significantly improve observational efficiency and data quality, enhance the detectability of nanohertz gravitational wave signals, and provide direct decision-making support for future PTA strategies to be adopted by the Square Kilometre Array (SKA).
