Multi-target deformation monitoring method and device and receiver

Abstract

The invention provides a multi-target 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: obtaining a composite signal formed by the superposition of a plurality of reflection sub-signals, wherein the plurality of reflection sub-signals comprise a target reflection sub-signal reflected by a target measured surface and the reflection sub-signal is a global navigation satellite system (GNSS) signal, and then determining the deformation quantity of the target measured surface according to a plurality of peak values of the composite signal. According to the invention, according to the relation between the peak value of the composite signal and the carrier phase of the reflection sub-signal, when the peak value of the composite signal changes, the carrier phase change of the target reflection sub-signal is obtained through inversion, so that the deformation quantity of the target measured surface is determined, and under the condition that multiple reflection signals are received at the same time, the receiver can still accurately obtain the deformation quantity of the measured surface. 本申请提供一种多目标形变监测方法、装置和接收机，涉及遥感测控技术领域，其中，该方法包括：获取由多个反射子信号叠加形成的复合信号，其中多个反射子信号中包括一个经目标被测面反射的目标反射子信号，反射子信号为全球导航卫星系统GNSS信号，然后根据复合信号的多个峰值，确定目标被测面的形变量。本申请可以根据复合信号的峰值与反射子信号的载波相位的关系，在复合信号的峰值变化时，反演得到目标反射子信号的载波相位变化，从而确定目标被测面的形变量，保证在同时接收到多个反射信号的情况下，接收机依然可以准确的得到被测面的形变量。
