What is the purpose of time-stamped data in the THAAD data flow between radar and launcher?

Time-stamped data give every radar measurement and launcher command a precise moment in time, providing a common reference for all parts of the THAAD data flow. That shared time base is what lets the system calibrate the radar array alignment, because it allows the launcher to compare when each array element produced a signal and how that maps to the launcher’s coordinate frame. By resolving relative delays and phase offsets between elements, the array’s boresight and geometry can be aligned accurately, which is essential for correct track fusion and intercept calculations. In short, the timestamps enable precise cross-element timing and temporal alignment with the launcher, which is why they are used for calibrating radar array alignment.
