[0023] Attached below Figure 1-4 The technology will be further described with specific examples to help understand the content of the present invention.
[0024] A measurement method for improving the distributed spatial resolution of an OFDR system, comprising the following steps,
[0025] S1. Two signals are collected respectively, one is a signal not containing strain information, which is a reference signal; the other is a signal containing strain information, which is a test signal.
[0026] S2. Divide the reference signal and the test signal into N equal parts according to a certain window size C in the distance domain;
[0027] S3. Using fast inverse Fourier transform for each piece of distance domain information of the reference signal and the test signal;
[0028] S4. Performing a cross-correlation operation on the reference signal after the inverse Fourier transform and the test signal to obtain a one-dimensional cross-correlation result;
[0029] S5. Steps S3-S...
