本文旨在评述现代防空雷达和监视雷达当前所采用的信号处理技术,而这些技术在将来很可能还适用。文章从提高监视性能的要求出发。讨论了现代雷达通行的新技术。重点是三座标雷达的信号编码技术、反杂波技术和电子抗干扰(ECCM)技术。同时也提到了这些技术的局限性。然后介绍了系统中预期会采用的新原理和新技术。讨论的范围包括:低截获概率、反反辐射导弹、反隐身技术、数字波束形成、自适应、高分辨力、多维处理和目标分类。并根据这些技术对提高监视性能是否达到预期的获益、可信程度以及技术风险等方面来评价每种技术的实战能力。本文对这些技术的描述,可由近几年来发表的大量参考文献所确证。
The purpose of this article is to review the current signal processing techniques used by modern air defense and surveillance radars, which are likely to apply in the future. The article starts from the requirement of improving the monitoring performance. Discussed the new technology of modern radar passage. The focus is on the signal coding, anti-clutter and electronic jamming (ECCM) techniques of the three-pole radar. Also mentioned are the limitations of these technologies. Then introduce the new principles and new technologies expected to be used in the system. The scope of the discussion includes: low probability of intercept, anti-anti-missile, anti-stealth technology, digital beamforming, adaptive, high resolution, multidimensional processing and target classification. And evaluate the actual combat capabilities of each of these technologies based on their benefits, credibleness, and technical risks in enhancing surveillance performance. The description of these techniques in this article can be corroborated by the large number of references published in recent years.
