Abstract
A system and method for detecting a suspicious object, including a wireless signal transmitter with first and second transmitter antennas, a first wireless signal receiver on an opposite side of the object from the transmitter having first and second receiver antennas, and a second wireless signal receiver on a same side of the object as the transmitter having a third receiver antenna. The transmitter may emit wireless signals from each of the transmitter antennas. The signals emitted by the first transmitter antenna may be received at the first and second receiver antennas. The signals emitted by both transmitter antennas may be received at the third receiver antenna. The object's material type may be determined based on channel state information of the wireless signals received at first receiver. A size of the object may be determined based on channel state information of the wireless signals received at the second receiver.
