Effect of Radar Undesirable Characteristics on the Performance of Spectral Feature Landmine Detection Technique

摘要

A factor that could affect the performance of ground penetrating radar for landmine detection is self-signature. The radar self-signature is created by the internal coupling of the radar itself and it appears constant in different scans. Although not varying much, the radar self-signature can create hyperbolic shape or anomaly pattern after ground alignment and thereby increasing the amount of false detections. This paper examines the effect of radar self-signature on the performance of the subspace spectral feature landmine detection algorithm. Experimental results in the presence of strong radar self-signatures will be given and performance comparison with the pre-screener that is based on anomaly detection will be made.
