本课题研究的是一种基于泰曼-格林( t - g )双光束干涉仪原理的光纤加速度计，系统主要包括：中心波长为1 . 31 m的ld相干光源、起传感作用的光纤柔性盘、光探测器( pin ) 、相位调制用的压电陶瓷以及信号处理系统。 - The wsf method and ml method can be used in direction finding of coherent sources . we find that tam has the widest direction finding range while the available direction finding ranges of the dsam , sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp are in a certain area centered at the look direction . the sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp can change the effective direction finding ranges by adjusting their inner parameters and furthermore they can improve the sidelobe suppression effect compared with the dsam method
得到tam的测向范围最宽,基于后五种简化阵列流形的测向方法其测向有效范围均是集中在波束指向附近的一定范围内,其中sam _ isp 、 sam _ aisp 、 sam _ gsp和sam _ agsp对应的测向范围可通过调整内部的参数进行相应的调整,相应地较dsam也可改善对旁瓣源的抑制效果。
