Description

technical field [0001] The invention relates to the technical field of microwave wireless communication, in particular to a cascadable wave control machine, a wave control machine system and a beam control method. Background technique [0002] The most notable feature of the phased array radar antenna is that the antenna beam scanning can be realized when the antenna array is not moving. The technical basis of highly self-adaptive capability, their realization all depends on the wave control machine. The traditional wave control design scheme is: when there are few phased array antenna array units, a centralized architecture is generally used; when there are many phased array antenna array units, a distributed architecture is generally used; in terms of circuit implementation, the early wave control The system is generally implemented by using discrete components. Later, single-chip microcomputers, DSPs, and FPGAs were used to design wave control systems. Recently, there ha...

[0003] But the centralized wave control design, when the array unit is relatively large, the amount of calculation is large, and the calculation time is long, which affects the speed of beam scanning; the distributed scheme is suitable for the situation where there are many array units, but it will bring more computing unit equipment. The wave control system built by discrete devices requires a large amount of equipment, which is not flexible enough, and it is difficult to realize the complex calculation of the beam; the single-chip microcomputer usually does not calculate the wave control code, but only arranges the phase according to the received wave control code; and Although the DSP can calculate the wave control code by itself, it cannot perform wave control code calculation and phase layout for each antenna channel in parallel; the custom wave control IC is not flexible enough, and its versatility and expansion ability are limited.

[0004] With the increase of antenna array units, the wiring from the wave control machine to the TR component becomes more and more complicated, and the calculation time of phase shift and amplitude attenuation increases accordingly, and the existing wave control machine can no longer meet the requirements
