일본 자위대의 전자전(電磁戰) 능력 과거와 현재. 그리고 미래

During the Russo-Japanese War in the early 20th century, Japan recognized the importance of electronic warfare, such as the withdrawal of the Japanese fleet due to the Russian Navy’s electronic warfare attack at Lushun Port. Japan plans to install and operate state-of-the-art electronic warfare equipment to monitor China, which is in territorial dispute in the South China Sea, and North Korea, which is developing nuclear and missile, and conduct electronic warfare in the mid- to long-term. Japan has the world’s third-largest electronic warfare capability and operates 33 aircraft that can be operated directly or indirectly with electronic warfare. It eliminated aging YS-11EB electronic electricity and introduce two RC-2s with the latest IT technology by 2022. Ground SIGINT facilities collect and process all communication and non-communication signals from neighboring countries transmitted and received from the ground, sea, and air at a total of 19 stations across Japan in the HF, VHF, UHF, and SHF bands. By 2023, eight ground-based electronic warfare missions will be established, extending from Hokkaido in the north to Okinawa in the south. Although there are no signs of development of UAV of electronic warfare, the Japan plans to introduce four global Hawk Block 30 (I) types of RQ-4B high-altitude UAV from 2022 with COMINT and ELINT collection sensors h accordance with the Japan’s defense plan. The RQ-4 Block 30 is equipped with Advanced Signals Intelligence Payload (ASIP), a communication and non-communication signals collection sensor, and can be used as ELINT and ESM equipment. The QZSS satellite, a regional satellite navigation system in Japan, consists of some of the same frequencies, signal structures, and diffusion code formats to be interchangeable with the U.S. GPS system. Because the QZSS system uses highly encrypted code, it is equipped with receivers for Izumo aircraft carriers, submarines, combat ships, rescue ships, attachments, aircraft, ground operational systems, and missiles as it is not disturbed by enemy interference or counterfeit signals. Japan does not seem to have any specific plans for acquiring SIGINT satellites to collect electronic signals yet, but it is strongly aware of the need. Since Japan continues to emphasize territorial protection through space and it is difficult to collect electronic signals from neighboring countries geopolitically, it is expected to secure its own SIGINT satellite by 2030 due to abundant funds, world’s best rocket and IT technology, and dose alliance with the U.S. Future war is developing into a soft kill concept rather than a hard kill concept of mass destruction. Conventional weapons, a high-tech hardware system, are important, but the development and operation of the electronic system that determines victory or defeat in the early stages of the war is one of Japan’s most important strategies to secure leadership in East Asia. In order to overcome the ability to carry out electronic warfare and signal information warfare,which are currently inferior to neighboring countries such as China and Russia, we will gradually develop an electronic warfare system by establishing a mid- to long-term plan with dose cooperation from the U.S.
