A distributed partition wall detection system combined with radar and vibration

Abstract

The invention discloses a distributed partition wall detection system combining radar and vibration, which comprises: a wall-penetrating radar sensor array, which is composed of M identical radar sensor probes, M≥3, which are used for autonomously transmitting and receiving electromagnetic waves. , and digitally collect the echo signals; the vibration sensor array is composed of N identical vibration sensor probes, N ≥ 2, which are used to detect micro-vibration and sound signals; the signal processor is used to receive radar sensor probes, vibration The data collected by the sensor probe completes at least one task of target detection, identification, tracking, positioning and indoor structural layout inversion; the control terminal is used for communication and control with the signal processor. The invention has the advantages of effectively improving the detection accuracy, improving the detection ability, improving the adaptability and the like.

Description

technical field [0001] The invention mainly relates to the field of detection technology, in particular to a distributed partition wall detection system combining radar and vibration. Background technique [0002] Through-the-wall radar is a device that emits electromagnetic waves in a specific frequency band, penetrates opaque non-metallic obstacles such as walls and ruins, and receives echo signals to detect, locate and track hidden targets behind obstacles. It is mainly used for urban emergency response In the fields of rescue and security, it is used to find and locate people hidden in buildings or behind obstacles, their activity characteristics, and internal structure information of buildings, so as to improve the perception of the environment, the survival success rate and survivability of one's own side . Compared with the concealed target detection methods based on sound signals, photoelectric signals, X-rays, etc., the through-wall radar has a long detection range...

AI Technical Summary

Problems solved by technology

[0005] 1) Poor environmental adaptability, through-wall radar cannot penetrate metal (mesh) wall obstacles, and cannot obtain environmental information behind it; vibration detection tracks the vibration reception of the sound source, and the rigidity, density and space of obstacles The degree of openness is relatively sensitive, and its ability to obtain information is poor in low-density, loose-structured obstacle application scenarios

[0006] 2) The situational awareness information acquisition ability is weak, and it is difficult for the through-wall radar to identify and distinguish the target; the vibration detection cannot know the target's position, attitude, building structure layout and other information

[0007] 3) The correct probability of obtaining environmental information is low

[0008] 4) The current through-the-wall radar and vibration detection equipment are self-contained systems and work independently. First, there are many equipment and modules carried on site, which require two people to operate or operate separately successively, which takes a long time and is inefficient; second, separate detection The data is independent, which needs to be artificially synthesized in the later stage, and analyzed and judged according to the results of the front and back detections. The correlation between the before and after results is missing, and a continuous and overall judgment cannot be formed; third, each has its own defects or scope of application, and the environment Poor adaptability
