“…The drone system proposed by the author in the previous study [ 39 ] is 1.0 m (L) × 1.0 m (W) × 0.7 m (H) in size, with a total weight of 5 kg (including batteries), and the magnetometer is fixed and installed at the center of the landing pole beneath the drone ( Figure 2 ). The distance of the magnetometer from the center of the drone is about 0.7 m ( Figure 2 a).…”

“…Previous research has suggested that landmines may be detected by attaching one magnetometer to a small UAV (sUAV) [ 37 , 38 ]. The conditions for detecting landmines involve measuring magnetic anomalies and adjusting for the distance between the landmine and the sUAV [ 39 ]. To increase the probability of landmine detection, it is essential to maintain a constant altitude, a short distance (1–2 m) from the surface [ 39 ].…”

We propose a magnetometer system fitted on an unmanned aerial vehicle (UAV, or drone) and a data-processing method for detecting metal antipersonnel landmines (M16) in the demilitarized zone (DMZ) in Korea, which is an undeveloped natural environment. The performance of the laser altimeter was improved so that the drone could fly at a low and stable altitude, even in a natural environment with dust and bushes, and a magnetometer was installed on a pendulum to minimize the effects of magnetic noise and vibration from the drone. At a flight altitude of 1 m, the criterion for M16 is 5 nT. Simple low-pass filtering eliminates magnetic swing noise due to pendulum motion, and the moving average method eliminates changes related to the heading of the magnetometer. Magnetic exploration was conducted in an actual mine-removal area near the DMZ in Korea, with nine magnetic anomalies of more than 5 nT detected and a variety of metallic substances found within a 1-m radius of each detection site. The proposed UAV-based landmine detection system is expected to reduce risk to detection personnel and shorten the landmine-detection period by providing accurate scientific information about the detection area prior to military landmine-detection efforts.

“…The number of drones in urban and rural airspaces will also amplify when passenger transportation [14], package delivery [15], agricultural surveillance and air cargo [16] are taken into account. From a military standpoint, border monitoring, landmine detection, logistic security, and military mission delivery require more drone injection into the airspace [17], [18]. Therefore, the future of air traffic will be crowded with UAS inclusion, and this requires new techniques and utilities in communication systems in order to detect aircraft in the dense air traffic regions rapidly.…”

The increasing trend in air traffic density will continue in the near future with the addition of different aerial vehicles. Before the Mode-S protocol, Mode A and Mode C were in use; however, the Mode A/C configuration was only usable in sparsely dense air traffic. One of the useful features of Mode-S is the ability of probabilistic interrogation. However, there has not yet been a sophisticated algorithm for many close aircraft. Considering a futuristic air environment with a swarm of drones and airbuses equipped with transponders, we utilized the probabilistic interrogation feature of Mode-S and designed an algorithm. The proposed algorithm is able to collect close aircraft information in a relatively short time. There has also been created a high-level Mode-S uplink and downlink communication simulator in order to exchange allcall communication and record the algorithm's performance in terms of time and number of interrogations sent.

“…Different types of sensors can be integrated within UAVs for landmine and IED detection. In this regard, metal detectors [6] and magnetometers [7] are limited to the detection of metallic targets. In contrast, Ground Penetrating Radar (GPR) sensors are capable of finding either metallic or nonmetallic targets, provided they have enough dielectric contrast with the medium in which they are buried.…”

Development of an Airborne-Based GPR System for Landmine and IED Detection: Antenna Analysis and Intercomparison

Airborne-based Ground Penetrating Radar (GPR) systems have proved to be an efficient solution for safe and accurate detection of buried threats such as Improvised Explosive Devices (IEDs) and anti-personnel and anti-tank landmines. The design of these prototypes is influenced by several parameters such as the working frequency band or the maximum weight and size of the payload to be placed on board the Unmanned Aerial Vehicle (UAV). In this sense, one of the main bottlenecks found in the design of these systems is the proper selection of the GPR antenna. This contribution focuses on the analysis of different Ultra Wideband (UWB) Vivaldi antennas and their performance in the context of an airborne-based GPR system. First, the Vivaldi antennas are characterized in terms of S 11 , radiation pattern, directivity, and phase center. Next, they are placed on board the implemented airborne-based GPR prototype to assess their impact on the detection capabilities of the system. In addition, other criteria such as the weight and size of the antennas are considered to make the final selection. Finally, the selected UWB Vivaldi antennas are tested in a realistic scenario.INDEX TERMS Ground Penetrating Radar (GPR), Ultra Wideband (UWB) antenna, Vivaldi antenna.
