Mine Detection Using Non-Sinusoidal Radar. Part 1. Spatial Analysis of Laboratory Test Data
Abstract
The interaction among UHF radiation, winter roadway conditions and buried mines was investigated in a refrigerated facility. The near-field spatial return from each target was unique. When the target was not in the near field the spatial return was not at all unique. Cobbles in the medium had little effect, but surface-thawed conditions significantly affected the spatial return, and the reflected signal strength and frequency content. The primary frequency content of the returned signal was either spread over a band broader than that of the transmitted primary frequencies, or completely outside of the primary detection band. We conclude that the complexity of winter roadway conditions requires (1) a much broader frequency band than is currently being considered, and (2) a more complex and adaptive background-removal, signal-enhancement scheme than is currently used. Further, more data are required describing the interaction of the winter media, UHF radiation, and buried mines so that adequate detection instrumentation can be developed.
