Rapid and efficient detection of surface mines, IED's (Improvised Explosive Devices) and UXO (Unexploded Ordnance) is of high priority in military conflicts. High range resolution laser radars combined with passive hyper/multispectral sensors offer an interesting concept to help solving this problem. This paper reports on laser radar data collection of various surface mines in different types of terrain.In order to evaluate the capability of 3 D imaging for detecting and classifying the objects of interest a scanning laser radar was used to scan mines and surrounding terrain with high angular and range resolution. These data were then fed into a laser radar model capable of generating range waveforms for a variety of system parameters and combinations of different targets and backgrounds. We can thus simulate a potential system by down sampling to relevant pixel sizes and laser/receiver characteristics. Data, simulations and examples will be presented.

“…Laser radar (LIDAR) systems are considered in many applications where accurate measurement of 3-D shape is desired, and MOMS is no exception in this respect. Previous work has demonstrated the vegetation penetration capabilities of LIDAR systems, which enable detection and recognition of objects behind or under obscuring vegetation [6]. In a typical mine detection scenario within MOMS, the distance between the target (i.e.…”

In this paper we study the potential of using deconvolution techniques on full-waveform laser radar data for pulse detection in cluttered environments, e.g. when a land-mine is partly occluded by vegetation. A pulse width greater than the distance between the reflecting surfaces within the footprint results in a signal that is composed by overlapping reflections that may be very difficult to analyze successfully with standard pulse detection techniques. We demonstrate that deconvolution improves the chance of successful decomposition of waveform signals into the components corresponding to the reflecting objects in the path of the laser beam. Experimental data were analyzed in terms of pulse extraction capability and distance accuracy. It was found that deconvolution increases the pulse extraction performance, but that surfaces closer than about 40% of the laser pulse width are still very difficult to detect and that the number of spurious, erroneously extracted, points is the price to pay for increased pulse detection probability.

“…Because of the specific property of active laser detection, the accuracy of active laser detection is higher than traditional detective means. It has been widely used in many different fields, for instance, land and resources survey [4], forest fire warning [5,6] and maritime search and rescue [7,8] etc. The active laser detecting imaging at complex weather conditions is becoming an urgent issue [9].…”
