Abstract
New generation phased array radars need to measure the relative time of arrival of broadband signals in different receivers very accurately. Because of the missmatch among different receiver chains there is a need of very precise calibration. Moreover, in digital receivers, these signals are sampled using frequencies that typically are close to the Nyquist limit. So the required accuracy is usually hundreds of times lower than the sampling period. In this paper, different methods to calculate the time delay between two signals are derived, and the results obtained with them are compared. The algorithm that leads to the best results is a modification of the MUSIC spectral estimator. This algorithm is studied in depth under different conditions.
