Abstract

The invention discloses a foundation microwave deformation monitoring system, which adopts a linear frequency modulation continuous wave system and utilizes components such as a DDS (Direct Digital Synthesizer) and a PLL (Phase Locked Loop) to generate emission signals, so that the system cost can be reduced while the size and the weight of equipment are reduced; the linear frequency modulation continuous wave system foundation microwave deformation monitoring radar samples the difference frequency signal after adaptive gain processing, and since the bandwidth of the difference frequency signal is far smaller than the baseband bandwidth of the transmitted signal, the sampling rate requirement on the ADC is greatly reduced, the data rate in the whole data chain is reduced, and the data transmission efficiency is improved. And high-performance transmission and storage elements are avoided, so that the system cost is further reduced. The system provided by the invention has the advantages of light weight, low cost, high real-time performance and high integration level.

Description

technical field [0001] The invention belongs to the field of micro-wave deformation monitoring, and more particularly, relates to a ground-based micro-wave deformation monitoring system. Background technique [0002] The existing ground-based micro-waveform deformation monitoring radar usually has two working modes: real aperture and synthetic aperture. Applications under the real aperture working mode include bridge amplitude and frequency monitoring, tower deformation monitoring, wind turbine blade vibration monitoring, etc. The synthetic aperture working mode includes topographic measurement and slope safety monitoring, dam and tailings dam safety monitoring, glacier, volcano detection Wait. The effective application of ground-based micro-wave deformation monitoring radar in safety monitoring makes it an important monitoring method to ensure the safety of people's lives and properties. [0003] Different from the characteristics of large scale and large revisit period o...
