1·This paper describes the distance measurement of optical surface based on optical coherence tomography.
介绍了利用光学相干层析技术实现光学表面间距测量的方法。
2·As the PN-code high performance of long period and the coherence, the very long distance and high precision ranging can be reached at the same time. Multi-target TT&C can be reached by CDMA of PN.
由于伪随机码固有的测距能力——其长周期和互相关特性，使得在测距距离和精度方面可以同时提高，采用码分多址技术可以实现对多个目标同时进行测控。
3·Various parameters insisting of spectrum of source, imaging distance and spatial coherence can influence visibility of fringes. Their referential values were presented in this paper.
条纹对比度受光源谱分布、成像距离、光源空间相干性这些因素的影响，对参数的研究给出了它们的参考值。
4·The close distance between moving and quiescent target spectrum caused by the moving carrier, Compensation was realized through the coherence signal parameter was changed.
当舰速造成动静目标回波频谱太近时，须改变其相参信号实现补偿。
