Landmine detection device based on UWB pulse electromagnetic waves

Abstract

The invention discloses a landmine detection device based on UWB pulse electromagnetic waves. The landmine detection device comprises a main processing module, a UWB signal transmitting assembly, a signal receiving and conditioning assembly, a high-speed ADC acquisition assembly, a single-pole double-throw switch K1 and a receiving and transmitting integrated antenna, wherein the main processing module conducts data interaction with the UWB signal transmitting assembly and the high-speed ADC acquisition assembly, the antenna serves as an electric field sensor to receive an echo signal in addition to a transmitting end for transmitting a pulse electromagnetic wave signal and can transmit the received signal to the signal conditioning assembly for signal processing, the signal is processed into data by the high-speed ADC acquisition assembly afterwards, then the data is transmitted to the main processing module, and whether a detection area contains a landmine or not is judged according to echo acquisition information. The landmine detection device has the beneficial effects that the detection device conducts detection by using ultra-wide-band pulse waves, transmitted electromagnetic pulses have the characteristics of rich frequency spectrum, wide frequency band, small width and the like, the anti-interference capability is strong, and the landmine detection precision is significantly improved.

Description

technical field [0001] The invention relates to the technical field of radio detection mines, in particular to a mine detection device based on UWB pulsed electromagnetic waves. Background technique [0002] At present, many countries pay more and more attention to mine detection research. Landmine is an explosive weapon. After the end of World War II, tens of thousands of various landmines have been left all over the world, posing a huge threat to people's lives and properties. , the countless cases of deaths due to landmines every year have greatly increased the need for demining in many regions of the world. For this reason, the requirements for mine detection technology are increasing day by day all over the world. [0003] UWB pulsed electromagnetic wave detection technology is a technology that achieves the purpose of detection by transmitting an ultra-wideband and ultra-narrow pulse electromagnetic wave with a rich spectrum to the ground, and then analyzing the echo ...

Problems solved by technology

However, the physical characteristics such as dielectric constant are highly variable, and the environmental interference factors are very large, which also makes the detection accuracy extremely unstable.

There are other ways to detect mines through radar waves. Radar waves usually use continuous waves to detect mines by performing spectrum analysis on the radar waves reflected from the ground. However, due to the heavy equipment, it is difficult for individual soldiers to operate. At the same time, the power requirement is high and the energy loss The most important thing is that the detection accuracy of a single mine is low. Usually, the radar wave mine detection method is usually used to determine the specific minefield in a large area.
