Radar Guidance
Radar guidance is a method of guiding a spacecraft or missile by using radar to track its position and velocity. The radar system sends out a signal that bounces off the target and returns to the radar receiver. By analyzing the time it takes for the signal to return and the Doppler shift of the signal, the radar system can determine the target's distance, speed, and direction of movement. This information is used to calculate the necessary adjustments to the spacecraft or missile's trajectory to keep it on course towards its target. Radar guidance is commonly used in missile defense systems, as well as in spacecraft navigation and landing on other planets.
