Patent ID: 7889077

Claim:
A method of detecting concealed objects, the method comprising: scanning a target with microwave electromagnetic radiation; receiving a reflected signal from the target, the reflected signal corresponding to the microwave electromagnetic radiation; conditioning and converting analog data related to the received signal to a digital data format; processing the digital data; determining a condition corresponding to the digital data; generating a signal for an operator indicating the condition, wherein scanning the target comprises: generating the electromagnetic radiation; transmitting the electromagnetic radiation to the target with a vertical polarization transmitter; connecting a detector to a vertical receiving element; generating a signal based on radiation reflected from the target in response to the transmitted electromagnetic radiation; transmitting the signal to a signal conditioning and conversion module; generating additional electromagnetic radiation; transmitting the additional electromagnetic radiation to the target with a horizontal polarization transmitter; connecting the detector to the horizontal receiving element; generating an additional signal based on radiation reflected from the target in response to the transmitted additional electromagnetic radiation; transmitting the additional signal to the signal conditioning and conversion module.
