“…Although not broadly applicable to many PR installations due to the large bandwidth and target size, the parameters were chosen to illustrate the effectiveness of the proposed algorithmic framework and to investigate phenomena particular to bistatic ISAR imaging. Implications of more narrowband operations – or, equivalently, moderate bandwidth with small targets – are examined in this paper's sequel [10].…”

“…All stages of TMC were estimated solely from the radar data, using the range and Doppler centroid approaches discussed previously. Part II [10] of the series will investigate the impact of track error on the RMC and its impact on backprojection operations.…”

“…13. Part II [10] of this series investigates the implications of the more narrowband imaging approach including experimental results of commercial airliners with a full‐scale ATSC PR testbed. Considerations of the motion compensation and autofocus algorithms are investigated in conjunction with common benchmarks for evaluating image focus such as contrast and entropy.…”

“…This formulation is well‐suited to such situations, but must be modified for the general case of multiple imaging geometries arising with distributed illuminators. This work deals primarily with the algorithms necessitated from the geometrical diversity, whereas part II [10] of the series investigates the narrow bandwidths often found with typical PR illuminators.…”

“…Applications to PR are considered throughout, and the final image reconstructions are evaluated for accuracy of target dimension estimation. Results of framework's application to 6 MHz data are also shown, which will be further investigated in Part II [10] of the series. Conclusions are drawn in Section 6.…”

Herein, we focus on convergent 6G communication, localization and sensing systems by identifying key technology enablers, discussing their underlying challenges, implementation issues, and recommending potential solutions. Moreover, we discuss exciting new opportunities for integrated localization and sensing applications, which will disrupt traditional design principles and revolutionize the way we live, interact with our environment, and do business. Regarding potential enabling technologies, 6G will continue to develop towards even higher frequency ranges, wider bandwidths, and massive antenna arrays. In turn, this will enable sensing solutions with very fine range, Doppler, and angular resolutions, as well as localization to cm-level degree of accuracy. Besides, new materials, device types, and reconfigurable surfaces will allow network operators to reshape and control the electromagnetic response of the environment. At the same time, machine learning and artificial intelligence will leverage the unprecedented availability of data and computing resources to tackle the biggest and hardest problems in wireless communication systems. As a result, 6G will be truly intelligent wireless systems that will provide not only ubiquitous communication but also empower high accuracy localization and high-resolution sensing services. They will become the catalyst for this revolution by bringing about a unique new set of features and service capabilities, where localization and sensing will coexist with communication, continuously sharing the available resources in time, frequency, and space. This work concludes by highlighting foundational research challenges, as well as implications and opportunities related to privacy, security, and trust.The associate editor coordinating the review of this manuscript and approving it for publication was Ahmed Farouk .

Radar can obtain high spatial resolution at large operating distances and its operation is largely independent from weather and lighting conditions. This makes it an important instrument in an ever-increasing number of applications requiring robust and reliable sensing of the environment. Due to the advancements in semiconductor technology and digital computation power, radar can obtain increasingly better position estimation accuracy, detection sensitivity, and target resolution. High-resolution imaging is an example of a rapidly advancing field of radar technology. Inverse synthetic aperture radar (ISAR) is an imaging technique that uses the motion of a target to obtain a high-resolution radar image of it. This paper presents a comprehensive review of past work and the state-of-the-art in ISAR imaging systems, algorithms, and applications. Starting from the early historical developments of simple monostatic range-Doppler imaging, we present the developments up to the current advanced spatially distributed imaging modalities and reconstruction algorithms. The list of references includes the most influential ISAR publications in the open literature up to early 2021.
