Multi-static radar refers to a radar network where multiple radar sensors are used simultaneously in different locations to track a target. Unlike traditional mono-static radar, which uses a single transmitter and receiver, multi-static radar systems enhance detection and tracking capabilities by leveraging several radar systems working together. This networked approach increases the accuracy and reliability of target identification and tracking, particularly in environments with high clutter or in the presence of sophisticated countermeasures. Multi-static radar is often used in military surveillance and advanced security systems.
