Distributed image reconstruction method of radio interference array

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0046] The original data used in this example is the data obtained by Karl G. Jansky VLA observation of supernova remnant 3C391 and then calibrated by the general astronomical application software CASA. The data format is Measurement Set, and the file name is 3c391_ctm_mosaic_spw0.ms.

[0047] First, view the data in the file 3c391_ctm_mosaic_spw0.ms, select the field of view of the target radio source, that is, the field ID number is 0; use CASA software to separate the observation data related to the field of view of the target radio source from the file 3c391_ctm_mosaic_spw0.ms and create a sub File 3c391_field0.ms.

[0048] Then, read the sub-file 3c391_field0.ms to obtain the observation frequency channel, uvw data, the re
