Experimental System and Experimental Results for Coast-ship Bi/multistatic Ground-wave Over-the-horizon Radar

This paper deals with a novel bi/multistatic radar system, which is spoken of as the bi/multistatic ground-wave (GW) over-the-horizon (OTH) radar based on the technique of synthetic impulse and aperture radar (SIAR). This radar can also be named as multi-input single-output (MISO) radar which uses several antennas to transmit orthogonal waves in one sector or the whole space and uses an omnidirectional antenna to receive target echoes. The receiver is installed on a moving ship and the transmit beams are formed through space-time signal processing in the receiver, which is the same as "passive position" without emitting energy. In this paper, an introduction is given to the operating principle of this radar as well as the experimental system and the results obtained
