Title: Detecting hidden objects
Inventor: BOWRING NICHOLAS
IPC: G01S7/41
Filed: 2010-09-17
Abstract: In order to detect and identify hidden objects, as in an airport security screening system, low power plane-polarised microwave radiation is directed towards a person and scattered radiation is detected by a detector sensitive to polarisation in an orthogonal plane (cross-polarisation). The transmitted and received planes of polarisation are varied, either by rotation of both transmitting and receiving antennas 104, 106 on a common platform, synchronised rotation of both, or switching between antennae having fixed poiarisations (fig. 8, 10). The transmitted frequency is modulated over a broad range (wide-band FMCW). The output signal of the receiver over a period of time is compared with expected returns in a neural network to identify the nature of any hidden object, and can distinguish a large knife, small knife, handgun, starter's pistol, mobile phone etc. The output signal may be amplitude only, or both transmitted and received signals may be heterodyned and the heterodyned signals mixed so as to determine the phase of the received signals as well (fig. 9, 10). An ultrasound sonar or stereoscopic camera may determine the distance to the person.
