Abstract

The invention provides a method and a system for determining the state parameters of a measured object. The method includes the following steps: at an acoustic transmitter, generating an acoustic signal, multiplying the acoustic signal by a spread spectrum pseudo-random code to obtain an acoustic ranging signal, sending out the acoustic ranging signal, and extracting the acoustic characteristic parameters of the acoustic transmitter; at an acoustic receiver, capturing the acoustic ranging signal, and extracting the acoustic characteristic parameters of the acoustic receiver; and detecting thestate parameters of a measured object based on the acoustic characteristic parameters of the acoustic transmitter and the acoustic characteristic parameters of the acoustic receiver. The spread spectrum technology is applied to acoustic measurement, and therefore, the state parameters of the measured object can be measured more accurately.

Description

technical field [0001] The invention belongs to the technical field of acoustic wave measurement, in particular to a method and system for determining state parameters of a measured object. Background technique [0002] At present, the systems mainly used for positioning include electromagnetic wave positioning system, acoustic wave positioning system, light positioning system and so on. [0003] Electromagnetic wave positioning systems (GPS, Bluetooth, wifi, etc.) are not accurate enough, especially in places with complex environments or places where electromagnetic waves cannot cover, it is almost impossible to locate. [0004] Due to the low positioning accuracy of pulse acoustic waves and weak anti-interference ability, and due to the Doppler effect, the positioning accuracy of acoustic positioning is not high. Contents of the invention [0005] Embodiments of the present invention provide a method and system for determining state parameters of a measured object. [...
