Title: Demands of communication in distributed radar


Distributed radars deploy multiple small aperture antennas on separated spaceborne, airborne, and ground-based platforms. Through sparse and flexible configurations, distributed radars can markedly improve the observation range, resolution, and accuracy. Therefore, they have obvious advantages in Earth and deep space observation. Nowadays, distributed radars have become one of the important directions of radar development.

As an indispensable part of distributed radar, communication networks support data transmission among each radar branch. With the development of system configuration and observation performance, distributed radars have new demands on communication. Firstly, different distributed radars have distinct spatial distances, structures, and collaborative relationships. It requires communication networks with flexible topology configurations. Then, transmission data will proportionally increase with the number of radar nodes and signal bandwidth. High-speed and high-reliability data transmission links are urgently needed. Finally, synchronization errors in distributed nodes can degrade the performance of signal-level processing. Therefore, it is necessary to build a high-precision time and frequency synchronization link.

This keynote speech focuses on demands of communication in distributed radar. Different working modes, network configurations, and processing methods of several typical distributed radars (spaceborne, airborne, etc.) will be firstly introduced. Their demands on configurations, transmission speeds, and access methods of communication networks will be deeply discussed.
