| 20100278008 | ACOUSTIC AND ULTRASONIC CONCEALED OBJECT DETECTION - An acoustic/ultrasonic detection system can detect, for example, an object concealed under the clothing of a subject. The system includes a signal generator configured to output an electrical signal. An acoustic/ultrasonic transducer can be configured to convert the electrical signal into an acoustic/ultrasonic signal, transmit the acoustic/ultrasonic signal, receive a reflected acoustic/ultrasonic signal from an object in the target area and convert the reflected acoustic/ultrasonic signal into a received electrical signal. The transducer is at least one of an air-coupled transducer and an electro-magnetic acoustic transducer. The system can also include an acoustic/ultrasonic antenna aperture operatively connected to the transducer and configured to focus the transmitted acoustic/ultrasonic signal to create a narrow beam in the target area, a processor configured to extract object information from the received electrical signal and an object indication device to provide an indication of a detected object based on the extracted object information. | 11-04-2010 |
| 20090271146 | MULTISTATIC CONCEALED OBJECT DETECTION - Concealed object detection using electromagnetic and acoustic multistatic imaging systems and methods. A method of simultaneously screening plural subjects for concealed objects includes transmitting a signal into a screening area where there is at least one subject to be screened having an associated object, receiving a reflected signal from the object when the object is located within the screening area, processing the reflected signal using multistatic Fourier space sampling and tomographic reconstruction to generate a three-dimensional image of the object and displaying the three-dimensional image. The transmitting and receiving are performed using a multi-directional array including at least three sensors. An object detection system includes a screening area, a multi-directional array including at least three sensors, a processor configured to execute multistatic Fourier space sampling and tomographic reconstruction and a display. | 10-29-2009 |
