It is our great pleasure to present you with this IET Radar, Sonar and Navigation special issue on the ‘Selected Papers from RADAR 2022—International Conference on Radar Systems (Edinburgh, UK)’.

RADAR 2022 took place at Murrayfield Stadium, Edinburgh, on 24–27 October 2022 as a prime opportunity for radar specialists at all career stages to update and enhance their knowledge on the latest developments in advanced radar systems. As such, RADAR 2022 was attended by over 250 delegates from 22 countries who joined the conference to explore the latest technologies in radar systems.

Key topics of RADAR 2022 included new radar trends and developments, bistatic and multistatic radar, target detection (with particular emphasis on drones), Constant False Alarm Rate algorithms, tracking before and after detection, low-frequency radar, waveform diversity, performance evaluation, virtual prototyping, and cognitive radar. Presentations covered the latest radar developments and were complimented by a set of outstanding tutorials given by world-leading radar experts on key elements of radar technology, a radar competition and keynote addresses from leading experts.

In total, 126 papers were published in the proceedings of RADAR 2022. Out of all these, the authors of the approximately 30 best papers, that scored the highest peer-review scores in the conference review selection, were invited to extend their conference papers into a journal article for this special issue.

This special issue contains 17 papers which are based on extended work presented at the conference on topics that include waveform design, estimation, passive radar, multistatic radar, Synthetic Aperture Radar (SAR), radar clutter and target signatures for detection and classification. The papers published in this special issue contain at least 40% new material compared to the work published in the RADAR 2022 conference proceedings and underwent a brand-new, rigorous, and robust peer-review process as set out by very high common IET and Wiley standards.

我们很高兴向您介绍 IET 雷达、声纳和导航特刊，主题为“RADAR 2022 年国际雷达系统会议（英国爱丁堡）论文选集”。

RADAR 2022 于 2022 年 10 月 24 日至 27 日在爱丁堡默里菲尔德体育场举行，为各个职业阶段的雷达专家提供了更新和增强对先进雷达系统最新发展的了解的绝佳机会。因此，来自 22 个国家的 250 多名代表参加了 RADAR 2022，他们共同探讨雷达系统的最新技术。

RADAR 2022 的关键主题包括新雷达趋势和发展、双基地和多基地雷达、目标检测（特别强调无人机）、恒定虚警率算法、检测前后跟踪、低频雷达、波形多样性、性能评估、虚拟原型和认知雷达。演讲涵盖了最新的雷达发展，并由世界领先的雷达专家就雷达技术的关键要素提供了一系列出色的教程、雷达竞赛以及领先专家的主题演讲。

RADAR 2022 会议论文集上总共发表了 126 篇论文。其中，在会议评审评选中获得最高同行评审分数的约 30 篇最佳论文的作者被邀请将其会议论文扩展到本期特刊的期刊文章。

本特刊包含 17 篇论文，这些论文基于会议上提出的扩展工作，主题包括波形设计、估计、无源雷达、多基地雷达、合成孔径雷达 (SAR)、雷达杂波以及用于检测和分类的目标特征。与 RADAR 2022 会议记录中发表的工作相比，本期特刊中发表的论文包含至少 40% 的新材料，并经过了由非常高的通用 IET 和 Wiley 制定的全新、严格和稳健的同行评审流程标准。
