What is a benefit of employing both passive and active ECM tactics?

Employing both passive and active Electronic Countermeasures (ECM) tactics significantly increases the effectiveness of electronic jamming and interception. Passive ECM involves techniques that do not directly transmit signals but instead rely on monitoring and detecting incoming threats to provide information for evasive actions or adjustments in tactics. This can involve radar warning receivers that alert operators to approaching enemy threats.

Active ECM, on the other hand, involves the deliberate transmission of electronic signals aimed at disrupting enemy radars and communications, effectively jamming their systems. When both methods are utilized in conjunction, they complement each other; passive measures can gather intelligence and information about threats while active measures can respond to those threats directly.

The synergy between these two approaches allows a vessel to effectively manage and counteract enemy electronic threats, making it more difficult for adversaries to target the ship accurately. The integration of both tactics leads to enhanced situational awareness and improves defensive measures against enemy electronic attacks.
