ECCM - Electronic Counter-Countermeasure

Japanese: ECCM - イーシーシーエム(英語表記)electronic counter-countermeasure
ECCM - Electronic Counter-Countermeasure
It refers to a method or device to counter ECM. For example, jamming a radar is ECM, and ECCM is when the radar changes frequency to avoid the jamming. As electronic devices advance and spread, ECM also becomes more complex and sophisticated, which requires the advancement and development of ECCM. It is now expected that the outcome of battles will be determined by electronic warfare, which is fought between these various devices.

Japanese:
ECMに対する対抗法あるいは装置をいう。たとえばレーダに対する妨害が ECMであり,これに対しレーダ側が周波数を変更して妨害を回避するのは ECCMである。電子装置が進歩し普及するに伴って,ECMも複雑巧妙なものとなり,その結果 ECCMの進歩発達を要求することになる。現在では戦闘の結果はこれら諸装置の間で戦われる電子戦 electronic warfareによって左右されると予想される。
