Embodiment
[0079] A phased array antenna beam control system based on distributed-centralized beam control mode of the present invention is applied to design a phased array antenna beam control system with 900 array units. In this embodiment, the number of arrays, that is, the number M of DSP beam control modules is 30, and the number P of array units in each sub-array is 30. The DSP chip selects the TMS320F2812 model of TI Company. According to this embodiment, the performance index of the phased array antenna beam control system based on the distributed-centralized beam control mode of the present invention is analyzed as follows:
[0080] In order to realize the operation speed of the wave control system is fast. The calculation time includes: the information transmission time between the beam control computer and the DSP beam control module is recorded as t 1 , the time of phase matching operation and phase compensation inside the DSP beam control module is recorded as t 2 , the i...
