Deformation monitoring method and device and receiver

Abstract

The invention provides a deformation monitoring method and device and a receiver, and relates to the technical field of remote sensing measurement and control, and the method comprises the steps: firstly, obtaining a direct signal and a reflected signal at a first moment, the reflected signal being a signal obtained after the direct signal is reflected by a measured surface, the direct signal being a global navigation satellite system GNSS signal, then obtaining a direct signal and a reflected signal at a second moment, and finally determining the deformation quantity of a measured surface according to the carrier phase of the direct signal and the carrier phase of the reflected signal at the first moment and the carrier phase of the direct signal and the carrier phase of the reflected signal at the second moment. According to the application, the GNSS signal with high measurement precision can be adopted to monitor deformation, and a signal transmitting end of a remote sensing type monitoring instrument can be omitted, so that the use cost of deformation monitoring can be reduced while the high measurement precision is ensured. 本申请提供一种形变监测方法、装置和接收机，涉及遥感测控技术领域，其中，该方法包括：首先获取第一时刻的直射信号和反射信号，其中反射信号为直射信号经被测面反射后的信号，直射信号为全球导航卫星系统GNSS信号，然后获取第二时刻的直射信号和反射信号，最后根据第一时刻的直射信号的载波相位和反射信号的载波相位，以及第二时刻的直射信号的载波相位和反射信号的载波相位，确定被测面的形变量。本申请可以采用具有高测量精度的GNSS信号监测形变，可以省去遥感式监测仪器的信号发射端，从而在保证高测量精度的同时可以降低形变监测的使用成本。
