Digital array radar (DAR) is the research and development focus all over the world, since it is much more powerful than conventional phased array radar. For example, the Air and Missile Defense Radar (AMDR), also known as the SPY-6, is a next-generation integrated radar including an active electrically scanned array (AESA) that is slated to be 30 times more powerful than the current SPY-1 phased array radar. In China, the Type 346 radar, a multi-function and dual-band naval active phased array radar (APAR), is also highly digitized. It has been proved that conventional radar systems can benefit greatly from digitalization. The performances, such as interference rejection, low sidelobe, target localization and tracking, have been made rapid progress.

For total flexibility of spatial processing, it is desired to perform full digitization, namely, digitization at element level. However, DAR systems are being developed towards high frequency, broad bandwidth and large scale. A full digitization demands thousands of digital receivers (or transceivers) per array face. This would bring us a number of key challenges, including the cost of thousands of digitizers (ADC/DAC), power consumption, channel equalization, processing and storage of huge data, physical structure and size, etc. Therefore, advanced system designs and related signal processing technologies for DAR are in urgent need of research.

This special issue seeks to bring together contributions from researchers and practitioners in the area of DAR. Prospective authors are invited to submit research papers on topics including, but not limited to:

● Affordable designs of DAR (low-precision quantization, hybrid digital and analog design, subarraylevel design, etc)

● Digital beamforming (DBF) and array pattern synthesis

● Target detection in DAR

● Synchronization and channel equalization for DAR

● Parameter estimation in DAR (DOA, frequency, doppler, etc)

● MIMO DAR (waveform design, detection, parameter estimation, etc)

● Multi-function designs for DAR

● Electronic counter-countermeasures (ECCM) in DAR

● Space-time adaptive processing (STAP)

All submissions will be peer reviewed according to the Journal of Beijing Institute of Technology guidelines. The contributions should be original and have not been published or submitted elsewhere. Submit your manuscript onhttps://mc03.manuscriptcentral.com/jbit. Prospective authors should consult the sitehttp://journal.bit.edu.cn/jbitfor guidelines and information on paper submission.
