摘要： A method for detecting a concealed material in a target comprising a body and the concealed material, the method comprising: emitting radio frequency (RF) energy toward a direction of the target, capturing a signal corresponding to a scattered RF energy reflected from the target, measuring a first mean signal level in a first frequency band of the signal, measuring a second mean signal level in a second frequency band of the signal, and detecting the concealed material when the difference between the first mean signal level and the second mean signal level is above a threshold.

摘要： An isolation barrier for reducing coupling between a transmitting antenna on a platform and a receiving antenna on the same platform. The isolation barrier expands the isolation capabilities of radar absorbing material (RAM) to the low frequency region by integrating dielectric loaded corrugations with the RAM. The isolation barrier includes a plurality of corrugations, each including a channel with two conductive walls and a conductive base, having a depth greater than a quarter of the wavelength corresponding to the low-frequency limit of the shared operating frequency band of the transmitting antenna and the receiving antenna. A layer of radar absorbing material (RAM) covers the corrugations.
