Zusammenfassung:The invention provides a crane structure vibration and deformation monitoring system and method based on phase coding microwave sensing, and the system comprises a microwave transceiver which transmits multi-channel linear frequency modulation continuous wave microwave signals at the same time through a transmitting antenna array, receives echo signals, and outputs multi-channel baseband signals; according to the control module, a coding phase shifter controls the direction of a synthetic wave beam, controls a microwave transceiver to transmit and receive a microwave signal and controls acquisition of a baseband signal; the signal processing module is used for processing the acquired baseband signals and extracting vibration displacement information of each to-be-measured position of the crane in the whole scanning vibration measurement process; and the display and storage module is used for displaying or storing system scanning angle distribution, vibration displacement sequence values or waveforms of all me
