Abstract
A method for detecting objects comprising radiation-absorbent material includes transmitting signals of two different frequencies to a target location and receiving an intermodulation product from the target location. The signals are transmitted via separate antennas connected with respective transmitters. The intermodulation product is received by a receiving antenna connected with a receiver and arranged to receive the intermodulation product reradiated from the target location. The intermodulation product comprises a harmonic of the two signals.
