【摘要】：依據(jù)GB-SAR傳感器運(yùn)行導(dǎo)軌與成像投影面的空間關(guān)系,分別推導(dǎo)了導(dǎo)軌中心線俯仰角和橫軸側(cè)傾角所引起的成像投影誤差的計(jì)算公式。計(jì)算結(jié)果表明,導(dǎo)軌安裝定位時(shí)產(chǎn)生的俯仰角通�？梢院雎圆挥�(jì),而成像投影誤差對(duì)導(dǎo)軌橫軸的側(cè)傾角更為敏感。在GB-SAR連續(xù)變形監(jiān)測應(yīng)用中,導(dǎo)軌的橫向姿態(tài)需做嚴(yán)格控制,確保其水平度。
[Abstract]:According to the spatial relationship between the guide rail and the imaging projection plane of the GB-SAR sensor, the calculation formulas of the imaging projection error caused by the pitch angle of the central line of the guide rail and the lateral inclination angle of the guide track are derived respectively.The calculation results show that the pitch angle produced by the guide rail is usually negligible and the imaging projection error is more sensitive to the lateral inclination angle of the guide rail axis.In the application of GB-SAR continuous deformation monitoring, the lateral attitude of the guide rail should be strictly controlled to ensure its flatness.
