摘要
由发射机(T)和接收机(R m)共站的单基地高频地波雷达增设分置的接收系统(R b)构成的T/R m-Rb双基地高频地波雷达系统用于海洋环境监测时,既可测得矢量流速度,又可消除风向模糊性,是目前高频地波雷达的发展趋势之一。该文首次从T/R m-Rb系统的探测能力与海流测量误差两方面分析最佳基线长度和最佳双基地角范围,从而确定其布站原则,即:在确定T/Rm单基地雷达的位置后,先根据T-Rb双基地雷达设计指标中的最大探测距离和确定基线长度,然后根据T/R m-Rb系统海流测量误差最小的原则确定最佳双基地角范围,从而确定T-Rb双基地雷达接收站Rb的位置。该布站原则可为双(多)基地高频地波雷达的海洋环境监测应用提供参考和依据。
If another separated receiver is added to a full monostatic high-frequency ground wave radar,a system can be got,one receiver operating in the monostatic mode,co-located with transmitter T,and another receiver operating in bistatic mode.The 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 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 monostatic radar is known,the optimal baseline length can be firstly determined according to the maximum range sum target of bistatic radar,then the optimal range of bistatic angle and the location of the bistatic receiver can be determined according to the minimum current measurement error of 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.
