Embodiment 1

[0037] Example 1: Please see again Figure 1-Figure 4 , the microstrip antenna array 100 is used for the detection function; the dual voltage regulator circuit 200 is installed inside the uniform antenna shell, and the dual voltage regulator circuit 200 reduces the background noise and the introduced noise; the continuous mean value module 300 obtains the signal strength in a stable state; abnormality evaluation The module 400 detects the cavity of the wall and the material change of the wall; the sound and light prompt module 500 provides the sound and light prompt function; the microstrip antenna array 100 includes a dielectric substrate, including an etching surface and a ground plane, and the surface of the etching surface is printed with The first metal patch arranged in a rectangular array, the first metal patch is etched with spiral slits, the surface of the ground plane is provided with the second metal patch, the bottom of the ground plane is provided with a rectangula...

Embodiment 2

[0038] Example 2: See again Figure 1-Figure 4 , the radar antenna adopts a microstrip antenna array 100, that is, the antenna surface is a plane, and a group of microstrip array elements for transmitting and receiving are integrated on it. Since the number of array elements is inversely proportional to the divergence angle, in order to improve the measurement accuracy, the divergence angle needs to be reduced. At the same time, Considering the difficulty of design and the high cost caused by the precision requirements of PCB casting, at present, 4*8 microstrip arrays are used for both transmission and reception.

Embodiment 3

[0039] Example 3: See again Figure 1-Figure 4 , the transmitting and receiving surface of the microstrip antenna is protected in a uniform antenna shell, and the medium is uniform in all directions, which ensures the measurement accuracy of the wall-penetrating radar, that is, the sensitivity to medium changes.

Abstract

The invention belongs to the technical field of detection radars, and particularly relates to a handheld microstrip antenna wall-penetrating radar. The system module of the radar device comprises a microstrip antenna array, a double voltage stabilizing circuit, a continuous mean value module, an abnormality evaluation module and an acousto-optic prompt module. The microstrip antenna array is mounted in the uniform antenna shell and is used for a detection function; the dual voltage stabilizing circuit is mounted in the uniform antenna shell and is used for reducing background noise and introduced noise; and the continuous mean value module is used for obtaining the signal intensity in a stable state. According to the handheld micro-strip antenna wall-penetrating radar, when the background noise voltage is smaller than 3 mV, the threshold value is set to be 25 mV, the accuracy of wall change measurement can reach 99%, namely the one-time passing rate of production is about 99%; the wall penetrating radar is controllable in production, reliable in quality, precise in measurement and simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of detection radar, in particular to a hand-held microstrip antenna wall detection radar. Background technique [0002] With the evolution of the market and the advancement of technology, there is an urgent need for a hand-held wall detection device, which should be small, hand-held, low-cost, and have a wide range of work. [0003] At present, there are mainly metal detectors for wall detection, that is, a magnetic field line coil, which can detect water pipes and metal on the wall, but cannot detect material changes or holes. Using the 24G millimeter-wave matrix antenna as a means of detecting walls can effectively detect changes in materials or holes on the walls. Of course, it can also detect whether there are water pipes or metal on the walls. Contents of the invention [0004] The invention provides the following technical solutions: [0005] A hand-held microstrip antenna wall detection radar, the...
