Since Russia launched its special military operation against Ukraine, this lightning strike that brought Ukraine's land and air forces to their knees in just 4 hours has been quite impressive. The modern warfare initiation method represented by the United States - electronic warfare - was repeatedly utilized by Russia in their encounters, and Russia has learned the essence of it. In this Russia-Ukraine conflict, the success of electronic warfare has enabled Russia to completely gain control of the air and sea supremacy over Ukraine, and has completely dominated the course of the war.

       Electronic countermeasures refer to various electronic measures and actions taken to weaken and damage the operational efficiency of the opponent's electronic equipment while ensuring the effective operation of one's own electronic equipment. It is also known as electronic warfare. Corresponding to the offensive launched by Russia, the first step was to use radio interference systems to interfere with the electronic equipment of the Ukrainian side, causing the opponent's wireless communication system to fail. The first wave of missile attacks that caused devastating damage to Ukraine's military radars, anti-aircraft missile bases, and air bases were the most direct manifestation of electronic warfare. There were also auxiliary means such as reconnaissance aircraft and satellite guidance, including the current use of early warning aircraft cooperating with armored forces for street fighting sweeps and rapid advances, which all fall under the category of electronic warfare.

       How to quickly disable the opponent's wireless communication, navigation and other wireless systems at the beginning of the war, and then quickly establish one's own emergency wireless communication system during the war, while effectively avoiding the wireless interference from the opponent, so as to ensure its continuous and stable operation in harsh environments, has largely played a crucial role in determining the outcome of the war.
