Systems, methods, and devices for detecting land mines and unexploded ordnance are disclosed. A first embodiment may be construed as a method that includes: inserting an antenna into the ground; transmitting an electromagnetic signal into the ground via the antenna; receiving a response via the antenna; and processing the response to generate an image which can be examined to determine whether a mine exists within proximity of the antenna.

A method of deactivating land mines buried in ground comprises projecting high-pressure water jets into ground, cutting through ground with the high-pressure water jets, and making at least one cut through a land mine or cutting through at least one land mine that had been under the ground, the cutting of the land mine reducing the performance of the land mine. The method may reduce the performance of the land mine by rendering the land mine inactive to normal detonation procedures for the land mine. To reach as many surface areas on the buried landmines, it is preferable that at least two high-pressure water jets are spaced apart are used to cut through the ground. The method may be practiced with the high-pressure water jet being carried on a vehicle and cutting is done in a line that is formed at least in part by movement of the vehicle over the ground while the high-pressure water jet is cutting ground. An apparatus for the reduction in effectiveness of land mines buried in ground may comprise a self-contained push-cart unit or a unit attached or attachable to a vehicle. A complete system could comprise a vehicle having a source of liquid, a high-pressure pump to move the liquid under high pressure, a nozzle directing a liquid jet path for the liquid, a support for the nozzle, abrasive delivery system, and nozzle being controllable to direct the liquid towards the ground while the nozzle is fixed relative to the vehicle.

A forwarding looking ground penetrating mine detection apparatus includes a radiation source for irradiating a sample of ground suspected of containing at least one mine with a plurality of frequency swept ground penetrating radar signals. A detector receives target signals backscattered from the ground responsive to the radar signal. The detector includes a time-frequency analyzer which transforms the target signals into a time-frequency image representation (TFR). In a preferred embodiment, the detector can include a wavelet packet transformer (WPT) for extracting time-frequency localized information from the TFR in the form of feature set constructed from a wavelet table. The apparatus can also include a data dimensionality reducer for selecting features to form a feature subset from the feature set, preferably based on reference to a training data set. A multilayer neural network classifier can be based on the feature subset, and be adaptable to the surrounding environment through learning.

Methods and apparatus for early detection and identification of a threat such as individuals carrying hidden explosive materials, land mines on roads, etc. are disclosed. Methods comprise transmitting radar signals in the direction of a potential threat, measuring the energy in reflected signals, dynamically generating a threat threshold value from signals received from multiple areas and comparing the energy in the reflected signals corresponding to different areas to the generated threat threshold value. The threat threshold value may be generated by averaging the weighted reflected energy measured from different areas during a single scan of a region including the different areas. The contribution to the threshold from different areas is weighted in some embodiments as a function of the distance from the transmitter and/or receiver to the particular area. Analysis of areas and treating different areas as segments facilitates accurate analysis and display of threat information.

A utility vehicle with underfloor structure giving protection from mine explosions. There is a wedge at the edge of the driver compartment which splits the detonation blast from a mine buried in the track of a front wheel. There is a multilayer stack, inboard of the wedge, which crushes upward to reduce the detonation wave from a mine buried under the vehicle. The stack comprises panels to catch the detonation wave and separated by spacers. Spacers are longitudinal stringers stacked above each other and welded, forming deep beams joined to bulkheads, making the vehicle's frame. The wedge also bolts to bulkheads, augmenting the frame. In cross section, the stack is curved, tapering off at each end to merge with the “V” of a wedge. The wedge crushes sideways under the detonation wave, providing protection at the edge of the driver compartment where stack material has run out.

The invention provides a smart mine. The smart mine is composed of a central control system, a detection sensing system against mine clearance, a power source, a safety insurance system, an ignition control system, accessory equipment and the like. The mine can sense information which is generated by all the measures of mine clearance through various sensors and be detonated instantaneously, and movement of the mine or radioscopy can also detonate the mine, i.e. the mine cannot be eliminated, destroyed, disabled and transferred by any measure of mine clearance. Thus, the mine can be reliably detonated at a scheduled time in a scheduled place. In addition, when the cipher instruction is input as required, a part of detection sensing devices and the function of timing detonation of the mine are disabled by the central control system, and the central control system starts the function of time-delay self-destruction at the same time, thus the mine can be transferred to a safe place within a limited period of time and then detonated and self-destroyed. A combat theory derived from the mine provided by the invention is discussed in the specification.
