GPR-Based Landmine Detection and Identification Using Multiple Features

الملخص EN

This paper presents a method to identify landmines in various burial conditions.

A ground penetration radar is used to generate data set, which is then processed to reduce the ground effect and noise to obtain landmine signals.

Principal components and Fourier coefficients of the landmine signals are computed, which are used as features of each landmine for detection and identification.

A database is constructed based on the features of various types of landmines and the ground conditions, including the different levels of moisture and types of ground and the burial depths of the landmines.

Detection and identification is performed by searching for features in the database.

For a robust decision, the counting method and the Mahalanobis distance-based likelihood ratio test method are employed.

Four landmines, different in size and material, are considered as examples that demonstrate the efficiency of the proposed method for detecting and identifying landmines.
