Disclosed is a method of determining subsurface temperatures of a surveyed region. The method comprises using a transmitter to transmit a pulsed electromagnetic signal into the ground; using a receiver to detect a return signal following interaction of said transmitted signal with features of the subsurface and determining one or more temperatures within the subsurface from the return signal. The temperature may be determined from a dielectric constant of a subsurface region, as determined from the received signal.

a barrier component, a metal detector component; and a base structure that physically connects to the barrier component and connects to the metal detector component, wherein the base structure distances the barrier component from the metal detector component a distance that prevents electromagnetic interference between the barrier component and the metal detector component. A monitoring component monitors at least one gate system parameter of the gate system and stores the at least one gate system parameter or transmits the at least one gate system parameter to a monitoring service over a network.

The present invention relates to a method for detecting (S) a target object using a detector (I) employing radiant energy, comprising the following steps: SI: placing an individual to be inspected in a first position within the detector (I); S2: acquiring first signals representative of a radiant energy when the individual to be inspected is in the first position; S3: placing the individual to be inspected in a second position within the detector (I), the second position being different from the first position; and S4: acquiring second signals representative of a radiant energy when the individual to be inspected is in the second position: and S5: on the basis of the first signals and of the second signals, producing an electronic image so as to determine whether the individual to be inspected is carrying, wearing or bearing a target object.
