Method, it is characterised in that：Processing locality sub-step described in step S2 includes following sub-step：
S201. dump control module reads data by GTX interfaces after receiving local playback command from memory module；
S202. dump control module stores data into main control computer module local hard disk by PCIe buses；
S203. the processing software of main control computer module completes the post-processing to playback of data and proof of algorithm；
Dump processing sub-step described in step S2 includes following sub-step：
S211. after receiving data dump order, master control reads the data in memory module with dump extension set control optical fiber interface；
S212. the optical fiber dump card of digital independent to dump extension set is carried out data DMA transfer by optical fiber interface using PCIe buses
To HBA cards；
Data are dumped to disk array by S213.HBA cards by FC interfaces again；
S214. the high-performance workstation of dump extension set carries out analyzing processing and proof of algorithm to the data for being dumped to disk array；
File management sub-step described in step S2 includes being deleted data, read and being formatted.
7. the digital bea mforming according to claim 6 received based on array signal verifies the data processing side of system
Method, it is characterised in that：Selection of the RF switch to signal source, is divided into following two situations in the step S12：
（1）When RF switch selects full coherent to receive the calibration signal of channel extension set as signal source, led to carry out calibration
It crosses RF switch and calibration signal work(is divided into 16 tunnels, being sent to full coherent after amplification with radio frequency method receives channel extension set；
（2）When RF switch selects the one of which of 3 groups of antenna arrays as signal source, by the signal of selection to penetrate after amplification
Frequency mode is sent to full coherent and receives channel extension set.
