1) airway observation
航路观测
2) obsever maneuvering trajectory
观测器机动航路
1.
Concerning on the problem of obsever maneuvering trajectory and target position tracking precision in bearing-only target motion analysis for single station,and based on target position tracking lower limit CRLB,the Geometric Dilution of Precision(GDOP) is proposed to be the optimal performance indicator.
针对在单站纯方位目标运动分析中观测器机动航路和定位与跟踪精度问题,基于目标定位跟踪精度下限CRLB,提出用精度几何散布GDOP作为优化性能指标,采用数值寻优计算的方法,对表达式较复杂的单观测器测向无源定位的定位误差下限进行数值计算,以找出影响定位精度的主要因素。
3) crusing observation
走航观测
1.
By means of ADCP crusing observation at Jiaozhou Bay mouth,the currents of both spring tide and neap respectively in spring and autumn are measured along the Tuandao-Xuejiadao transection at the Jiaozhou Bay mouth.
通过ADCP(声学多普勒海流剖面仪)在胶州湾湾口走航观测,得到胶州湾口团岛到薛家岛断面在春季和秋季的大潮、小潮的海流资料,对观测的流量值进行时间积分,从而得到胶州湾的纳潮量。
