Advanced Array Antenna Design and Signal Processing Techniques

Dear Colleagues,

Array antennas and signal processing techniques are of critical importance in modern electronic systems, such as wireless communication system, vehicular system, unmanned aerial system, radar, etc. Firstly, as the front end of an electronic system, an antenna with wide bandwidth, high gain, and compact size is always required to guarantee the high level of system performance. Moreover, a limited and complex electromagnetic environment reserved for an antenna location creates higher requirements for antenna performance. Secondly, signal processing techniques are essential to enhance the desired signal and mitigate nuisance signals, thus improving the system performance. The performance of electronic systems can be further improved by properly utilizing signal processing techniques. The increasing development of radar and communication systems further promotes new technologies in antenna design and array signal processing. A great number of research groups are working on such active and frontier topics. With the in-depth investigations of array antenna, several novel array antenna frameworks are born, including the frequency diverse array, waveform diverse array, massive multiple-input multiple-output array, opportunistic array, and so on. To further promote the innovative development of basic theories and key technologies of antennas and array signal processing techniques, this Special Issue aims to gather the latest advanced research progress in the field of antenna design and array signal processing techniques for various applications, especially for remote sensing. The types of collected papers include academic papers and review articles on the latest technological achievements.
