How does the Patriot system determine the target's trajectory?

The Patriot system determines the target's trajectory primarily through sophisticated radar and tracking systems. These systems continuously monitor and track airborne threats, such as missiles or aircraft, by emitting radar waves and analyzing the reflections that bounce back. This process provides real-time data about the target's position, speed, and direction, allowing the Patriot system to predict where the target will be in the future.

By leveraging advanced algorithms and signal processing, the radar can calculate the trajectory of the target with high accuracy, enabling effective interception. This automated capability improves response times and enhances the effectiveness of the missile defense system compared to manual methods. Other methods like visual observation or manual calculations lack the precision and immediacy required for effective target tracking, while satellite data, although useful for broader surveillance, is not the primary means employed by the Patriot system for real-time tracking and interception.
