Electronic Countermeasures (ECM) are techniques used to disrupt or deceive enemy radar and communication systems. They can involve jamming signals, which prevents the enemy from receiving or transmitting information effectively. ECM is crucial in military operations to protect assets and ensure the safety of personnel. ECM can also include the use of decoys, which mimic real targets to mislead enemy sensors. This technology is often employed in conjunction with other defense systems to enhance overall effectiveness. By utilizing ECM, military forces can gain a strategic advantage in various combat scenarios, safeguarding their operations against threats.
