众所周知,电子战(EW)和电子支援措施(ESM)在现代战争中占有愈来愈重要的位置。由于EM所面临的电磁环境日益复杂,所以对侦察与识别手段的要求也更加苛刻。其中主要问题是要求频率覆盖宽、测量精度高、处理容量大、反应速度快以及能够分辨出同时到达的各种信号等等。国外在发展EW技术方面的竞争异常激烈。随着电子工业技术和工艺水平的提高,作为EW重要手段的测量接收机也在不断更新和发展。近来国外对瞬时测频接收机(IFMR)和集成声光频谱分析器(IOSA)都陆续有所报导。这些技术和设备正在不断地完善,已从实验走向实用,如能配合使用几种不同的接收机似可较好地达到现代电子战的要求。本期选载了三篇有关文献:1.宽带ESM接收系统,2.电子战和瞬时频率测量接收机,3.集成光学射频频谱分析器,以供读者了解当前国外的技术水平和某些战术使用方面的观点。
As we all know, electronic warfare (EW) and electronic support measures (ESM) occupy an increasingly important position in the modern war. Due to the increasingly complex electromagnetic environment EM faces, the requirements for reconnaissance and identification methods are also more stringent. One of the major issues is the requirement of wide frequency coverage, high measurement accuracy, large processing capacity, fast response, and the ability to distinguish between various signals arriving simultaneously. Foreign competition in the development of EW technology is extremely fierce. As the level of technology and technology in the electronics industry increases, receivers for measurement as an important means of EW are constantly being updated and developed. Recently, foreign countries have reported instantaneous frequency measurement receiver (IFMR) and integrated acousto-optic spectrum analyzer (IOSA). These technologies and devices are constantly being improved and have been experimentally practiced. If they can be used in combination with several different receivers, the requirements of modern electronic warfare can be better achieved. This issue contains three articles: 1. Broadband ESM receiving system 2. Electronic warfare and instantaneous frequency measurement receiver 3. Integrated optical radio frequency spectrum analyzer for readers to understand the current foreign technical level and certain tactics Use of the point of view.
