Abstract EN
The profile recovery is an important work in X-ray pulsar-based navigation.
It is a key step for the analysis on the pulsar signal’s characteristic and the computing of time of arrival (TOA).
This paper makes an argument for an algorithm based on the tracking-differentiator (TD) to recover the profile from the low Signal-to-Noise Ratio (SNR) signals.
In the method, a TD filter with cascade structure is designed which has very low phase delay and amplitude distortion.
In the simulation experiment, two typical pulsars (PSR B0531+21 and PSR B1937+21) are used to verify the algorithm’s performance.
The simulation results show that the method satisfies the application requirements in the aspects of SNR and profile fidelity.
By processing the data collected by the Rossi X-Ray Timing Explorer (RXTE) satellite in space, similar results can also be achieved.
