Abstract
Special attention has been devoted to joint wireless communication and radar sensing systems in recent years. However, since wireless communication and radar have conflict requirements in terms of waveforms, transceiver developments and signal processing algorithms, realization of this system concept is still a great challenge. In this paper, we introduce airborne multiple-input multiple-output (MIMO) radar, along with the space time coding (STC) waveform scheme, for the implementation of joint wireless communication and synthetic aperture radar (SAR) imaging. The proposed system, which simultaneously transmits mutually orthogonal waveforms with reconfigurable channels, can acquire adequate degrees of freedom. Thereby, it becomes a feasible method to perform both data transmission and SAR imaging at the same time without intra-modal interference. Theoretical analysis is validated by experimental flight results. Through our analysis, we aim to open up a new perspective of using MIMO radar to realize joint wireless communication and SAR imaging
