The ability of a RADAR system to rapidly tune from one operating frequency to another is defined as frequency agility. This capability allows the RADAR to evade electronic countermeasures and interference by changing frequencies quickly, making it harder for adversaries to predict or jam its signals. Frequency agility enhances the system's resilience against detection and improves its overall effectiveness in dynamic electronic warfare environments.

This concept is crucial for modern RADAR systems, particularly in military applications where survivability and versatility are essential. It allows for optimal performance in various operational scenarios and accommodates different tactical needs.
