| 摘 要： | 根据条带拼接网的误差特点,构建了以ping为单位的条带网交叉点差值误差模型,导出了条带拼接网的秩亏网平差模型,并分析了秩亏的原因。根据条带拼接网ping的相交情况,推导了基于ping的阶段平差公式,给出了条带拼接网的系统误差改正模型。实例计算表明,条带拼接秩亏网平差模型可有效地探测ping、条带以及整个测区的系统参数。

| Abstract: | Combining neighboring swaths is an important step in swath sounding data processing.The error structure of ping in swath sounding is brought forward.Then the adjustment defect model is given for the swath combination net,and we poin out the lack of datum data is main factor to make the adjustment mode defect.To solve the large equation based pings,the formulae is derived based on the theory of adjustment division.A practical example for detecting systematic errors is given.Experimertal results show that the... |
