摘　　要：针对北斗探测系统与L波段雷达在测风体制上的差异,通过同球施放与前后施放两种方法进行动态试验,采用插值法,对比了同一高度北斗测风方式与雷达测风方式、无线电经纬仪测风方式所探测高空风数据的误差。通过对比分析探测资料发现:北斗探测系统与L波段雷达所测空中风的变化趋势与幅度大体一致;两者的经向风差值较小,而纬向风差值较大;与L波段雷达相比,北斗探测系统的经向风和纬向风均偏小;北斗探测系统对空中短时风切变过程的探测更有效。In view of the difference in wind measurement system between Beidou detection system and L-band radar,the dynamic test is carried out by using the same balloon and one after another balloon,separately.The errors of high-altitude wind data detected by the Beidou,radar and radio theodolite wind measurement method at the same height are compared by using interpolation method.Through the comparative analysis of detection data,it is found that,the change trend and amplitude of air wind measured by the Beidou detection system and L-band radar are generally consistent;the difference in meridional wind between the two is relatively small,while the difference in meridional wind is relatively large;compared with L-band radar,the meridional and latitudinal winds of the Beidou detection system are smaller;the detection of short-term wind shear process by the Beidou detection system is more effective.
