摘要
在干涉仪传统测向理论基础上,分析了极限条件下双站时差测量与单基线干涉仪测向在数学模型上的等价性。利用调制信号的频域相位提取时差而得到来波方向信息,阐述干涉仪测向的时差分析理论,并通过仿真分析验证该理论的有效性,从而为干涉仪测向更加广泛的应用提供了新的思路。
The traditional direction measure theory for interferometer is introduced. The equivalence between time difference measure of two stations and direction measure of single- baseline interferometer is analyzed on the limited condition. The direction information is obtained through time difference gotten from the phase on frequency domain of signals. Therefore, a direction measure theoretics based on time difference analysis for interferometer is explained. The simulation demonstrates the validity of this theory. It is novel for wide utilization of interferometer direction measure.
