Embodiment 1
[0056] see figure 2 , which shows the correction coefficient acquisition method in the first embodiment of the present invention, which can be applied to an array receiving system, and the method is specifically:
[0057] Step S01, obtaining the current received signals received by each receiving channel in real time under a plurality of preset target frequency bands;
[0058] Step S02, establishing the time synchronization between the current received signal and the common reference signal, and calculating the actual amplitude and phase values of the synchronized carrier signal, so as to obtain the actual amplitude and phase values of each of the receiving channels in each target frequency band ;
[0059] Step S03 , calculating the amplitude and phase correction coefficients of each of the receiving channels in the entire frequency band according to the actual amplitude and phase values of each of the receiving channels in each target frequency band and the preset amp...
Embodiment 2
[0101] Another aspect of the present invention also provides an array receiving system, please refer to image 3 , shows the array receiving system in the second embodiment of the present invention, the array receiving system is a multi-channel full-band receiving system, and the array receiving system specifically includes:
[0102] A reference signal module, configured to generate a common reference signal required for time synchronization of each receiving channel;
[0103] A plurality of synchronous acquisition modules, each of the receiving channels is provided with a corresponding synchronous acquisition module, and the synchronous acquisition module is used to obtain the current received signal received by the corresponding receiving channel in real time under a plurality of preset target frequency bands , and establishing time synchronization between the current received signal and the common reference signal;
[0104] A plurality of carrier amplitude and phase estima...
