摘　　要：为了分析无源北斗探空测风系统的误差,研究减小其测风误差的方法,从分析"北斗一号"无源定位接收机测距定位误差入手,分析了"北斗一号"无源定位的误差来源。对与卫星、卫星信号传播、气压计算高度和接收机有关的误差这4个影响伪距测量精度的因子进行了研究,分析了其误差性质和提高伪距测量精度的方法。试验表明,"北斗一号"无源定位误差小于100 m,则"北斗一号"探空测风系统误差小于2 m/s。In order to analyse the error of passive BEIDOU sounding and wind measurement system and to investigate the way of minishing errors in wind finding,the error of the passive location receiver was analyzed.Errors about the satellite,the transmitting of satellite signal,retrieval of height from the air pressure and the receiver were discussed.The characteristics of errors and the way of improving the pseudo-range precision were analysed.The research and experimental results indicate that if the error in the pa...
