【摘要】 为了在常规雷达上得到三维矢量风场,在基于雷达回波相关跟踪的TREC(Tracking Radar Echo byCorrelation)技术的基础上,文中发展了一种基于体相关的相关方法追踪雷达回波运动(Enhanced TrackingRadar Echo by Correlation)的技术,简称ETREC,取得了初步成果,同时利用DirectX技术开发了一套三维风场显示系统。通过个例分析表明,ETREC三维矢量场能够显示出复杂气象条件下对流云系内的气流运动。更多还原

【Abstract】 To get the three-dimensional retrieval of wind field from the conventional radar,an extension of TREC(Tracking Radar Echo by Correlations)technique,named Enhanced Tracking Radar Echo by Correlations(ETREC) is presented,in which three-dimensional echoes are tracked,by finding the maxima in the cross-correlation function between two scanning data.Example is presented where the ETREC algorithm was applied,it is the convective weather on 14 April 2007 from Chengdu XDR-21 radar.It is found that the ETREC algorithm could yield three-dimensional retrieval of wind field,but there is still some questions that need to be solved.The future work maybe increases the running speed of this software,and meanwhile improves the accuracy of the wind field.更多还原
