Abstract：If another separated receiver is added to a full monostatic high-frequency ground wave radar, a T/Rm-Rb system can be got, one receiver Rm operating in the monostatic mode, co-located with transmitter T, and another receiver Rb operating in bistatic mode. The T/Rm-Rb system for ocean environment remote sensing can not only measure the current vector velocity, but also eliminate the wind direction ambiguity. It is one of the trend in development of high-frequency ground wave radar. In this paper, the distribution principle of T/Rm-Rb system is determined from the optimal baseline length and optimal range of bistatic angle, which are analyzed from the angle of radar detection ability and current measurement error. That is: if the location of T/Rm monostatic radar is known, the optimal baseline length can be firstly determined according to the maximum range sum target of T-Rb bistatic radar, then the optimal range of bistatic angle and the location of the bistatic receiver Rb can be determined according to the minimum current measurement error of T/Rm-Rb system. The distribution principle obtained in this paper will provide useful reference for the application of bistatic (or multi-static) high-frequency ground wave radar to ocean environment remote sensing.
