A tomographic imager based on an infinite state machine ordered cloud signal

Abstract

The invention provides a tomographic scanning imager based on ordered cloud signals of an infinite state machine. The tomographic scanning imager comprises an infinite state machine ordered cloud signal generator (1),a signal coupler,a radio frequency transmitting module (2),a switch combination module (3),a receiving module and a relevant interference imaging processing module (8). The infinite state machine ordered cloud signal generator (1) is used for generating the first ordered cloud signals; the signal coupler is used for converting the first ordered cloud signals into the second ordered cloud signals; the radio frequency transmitting module (2) is used for receiving the first ordered cloud signals,converting the first ordered cloud signals into radio frequency and transmitting theradio frequency to the outside; the switch combination module (3) is used for controlling the operation time sequence of the receiving module and eliminating clutter of the ordered cloud signals; thereceiving module is used for performing delay and gain processing on the ordered cloud signals,and the processed signals are transmitted to the relevant interference imaging processing module (8). Therelevant interference imaging processing module (8) is used for completing tomographic imaging of a detection target.

Description

technical field [0001] The invention relates to the technical field of radar remote sensing, in particular to a tomography imager based on ordered cloud signals of an infinite state machine. Background technique [0002] The tomography scanner is a non-destructive detection instrument for detecting subsurface structures. It uses the penetration ability of electromagnetic waves to the surface to emit electromagnetic waves carrying ordered cloud signals from the surface to the interior. The electromagnetic waves are scattered on the interface where the properties of the medium change. By receiving the scattered echo signal, according to its time delay, shape and spectrum characteristics and other parameters, the target position, medium structure and properties are interpreted, and on the basis of data processing, the image recovery and reconstruction technology is applied to scan and image the target processing, in order to achieve a true and intuitive reproduction of the subs...

AI Technical Summary

Problems solved by technology

[0003] Due to the use of coherent detection technology based on shock pulse signal and frequency-modulated continuous wave signal in the existing technology, the echo signal is continuous and coherent, so it is always affected by various clutter

Clutter is usually very strong, and it is difficult to eliminate as the position changes, making target detection difficult

Almost all existing means are difficult to get rid of the above effects
