Targets Characterization by Radars

Dear Colleagues,

The radiation characteristic of radar targets is widely utilized in the applications of target classification/recognition, target detection algorithm design, target structure recovery, and radar system simulation. The target radiation characteristics, e.g., high resolution range profile (HRRP) for target classification/recognition and target radar cross section (RCS) statistics for detection algorithm design, can be extracted through multiple-aspect, multiple-polarization, and long-term radar observations. However, an increasing number of complicated targets have emerged in recent years, including the hypersonic vehicle and unmanned aerial vehicle (UAV) cluster. As a result, there is a need to study the radiation characteristics of these targets. Moreover, the radiation characteristic is not the only feature that can be extracted from the radar echoes. For example, the behavior characteristic of the UAV cluster can be obtained through long-term and high-resolution radar observations. Such behavior characteristics can reveal more in-depth information about the target, which is beneficial to enlarge the application area of radars. Therefore, research on the methods to extract new characteristics of target from radar echoes is required.

This Special Issue is devoted to highlighting the most advanced research in radar target characterization technology, methodology, and applications. Papers dealing with fundamental theoretical analyses as well as those demonstrating their application to real-world and/or emerging problems will be welcome. The journal publishes original papers and invited review articles in all areas related to the target characterization of radar including, but not limited to, the following suggested topics:

• Radar target scattering mechanism and characterization;
• Radar target polarization characterization;
• Target structure recovery through radar;
• Target behavior characterization through radar;
• Target characterization through high/low-resolution radar;
• Hypersonic target characterization;
• Cluster target characterization through radar;
• Application of radar target characterization.
