摘要：

This paper presents wide bandwidth, time decay responses from low metal content (LMC) mines, LMC mine simulates, and ground voids. Measurements were collected both in the laboratory and in the field. The target time decay responses were measured with the Johns Hopkins University Applied Physics Laboratory developed Electromagnetic Target Discriminator (ETD) sensor developed for the US Army CECOM/NVSED. The ETD sensor has demonstrated the ability to measure metal target decay times starting approximately 3 to 5 mus after the transmitter current is turned off and metal target decay time constants as short as 1.4 mus.
