Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.
[0020] A method for dividing analysis windows of multi-telemetry parameters of a spacecraft provided by the present invention specifically includes the following steps:
[0021] The first step: multi-parameter cycle correlation analysis;
[0022] The second step: generate the segmentation features of the benchmark parameters;
[0023] The third step: use the reference parameters to complete the multi-parameter window division.
[0024] The first step as mentioned above specifically includes the following steps:
[0025] Step 1.1: The spacecraft telemetry data analysis includes a total of n telemetry parameters, marked as p 1 ,p 2 ,...,p n . For each telemetry parameter p i(1≤i≤n) preprocessing at equal intervals, and because the sampling period used by different para...
