System Design and Performance Test for Phased Array Radar Communication

Radar communication integration seems promising to meet multiple mission requirements, reduce the number of antennas, and improve the utilization of spectrum resources. However, proper system design is required to obtain these advantages. In this paper, we propose a radar communication framework which allows radar and communication to share aperture, beamforming, spectrum, and resource scheduling. Moreover, a burst communication waveform is proposed to overcome the impact of saturated power amplifiers and improve performance. Moreover, we develop a radar communication test system. Test results validate the feasibility and effect of our proposed radar communication framework. Besides, in the test radar communication integration system, over-the-horizon scattering communications have been realized.
