Technical Field

[0001] The utility model belongs to the technical field of signal processing preparation, and particularly relates to a low-cost high-power TR phased array transceiver system. Background Technique

[0002] The TR phased array transceiver system, full name Transmit / Receive phased array transceiver system, is a core component in modern radar technology. This system consists of a large number of T / R (Transmit / Receive) components. Each T / R component can independently transmit and receive electromagnetic waves, and realizes the scanning and shaping of radar beams in space by adjusting the amplitude and phase of signals.

[0003] The high-power TR phased array transceiver system (where TR represents Transmitter and Receiver, that is, transmission and reception) plays a key role in electromagnetic wave signal processing. However, regarding the problem that the free conversion of various polarization modes of electromagnetic wave signals cannot be achieved, although digital beamforming technology can improve the flexibility and performance of the system to a certain extent, it still faces challenges in polarization conversion. Especially when complex polarization mode conversion is required, more advanced signal processing algorithms and more powerful computing capabilities may be needed. Polarization synthesis and decomposition: In the signal processing process, the conversion between different polarization modes can be achieved through polarization synthesis and decomposition technology. However, this method requires accurate polarization measurement and calibration, as well as complex signal processing algorithms, which may be difficult to implement or costly in practical applications.
