Interference type deformation monitoring method and device and receiver

Abstract

The invention provides an interference type 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 first interference signal, and then obtaining a second interference signal, wherein the first interference signal and the second interference signal are formed by a direct signal and a reflection signal corresponding to the direct signal, the reflected signal corresponding to the direct signal is a signal obtained after the direct signal is reflected by a measured surface, the direct signal is a global navigation satellite system (GNSS) signal, the emission angle of the direct signal forming the first interference signal is the same as the emission angle of the direct signal forming the second interference signal, and the emission time is different, and finally, the deformation quantity of the measured surface is determined according to the first carrier-to-noise ratio sequence of the first interference signal and the second carrier-to-noise ratio sequence of the second interference signal. Interference signals do not need to be continuously detected, so that the reliability of the receiver can be effectively improved. 本申请提供一种干涉式形变监测方法、装置和接收机，涉及遥感测控技术领域，其中，该方法包括：首先获得第一干涉信号，然后获得第二干涉信号，其中，第一干涉信号和第二干涉信号都是由直射信号和直射信号对应的反射信号形成的，直射信号对应的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，形成第一干涉信号的直射信号的发射角度和形成第二干涉信号的直射信号的发射角度相同，发射时间不同，最后根据第一干涉信号的第一载噪比序列和第二干涉信号的第二载噪比序列，确定被测面的形变量。本申请不需要连续检测干涉信号，因此可以有效提高接收机的可靠性。
