Abstract :
In this paper, we propose a concept of multiple-input multiple-output high frequency surface wave radar (MIMO-HFSWR) system with widely separated antennas transmitting and receiving the sparse frequency waveforms. The proposed concept obtains several advantages over the conventional HFSWR system such as finer resolutions and better flexibility. The ambiguity function (AF) was derived in detail to assess the proposed system. The impacts of Doppler effect and the geometry configuration factor are also studied.
