| 20080261536 | AUTOMATIC DELAY CALIBRATION AND TRACKING FOR ULTRA-WIDEBAND ANTENNA ARRAY - A method for determining changes in internal delays of RF units, the RF units including a plurality of receivers and transmitters. The method includes providing initial direct signals' time of arrivals of the RF units initial internal delays of the RF units. Following this, each transmitter transmitting a direct signal, and the real-time direct signal's time of arrivals of the RF units, are measured. Then, changes in internal delays of the RF units are calculated based on the real-time direct signals' time of arrivals and initial direct signals' time of arrivals. And finally, real-time internal delays of the RF units are calculated based on the changes in internal delays and the initial internal delays of the RF units. | 10-23-2008 |
| 20090033548 | System and method for volume visualization in through-the-obstacle imaging system - Herewith disclosed a computerized method of volume visualization, a volume visualization unit and through-the-obstacle imaging system capable of volume visualization. The method of volume visualization comprises obtaining one or more volumetric data sets corresponding to physical inputs informative, at least, of a part of an imaging scene concealed by one or more obstacles and obtained by a sensor array; obtaining data informative of position and/or orientation of the sensor array corresponding to said obtained physical inputs; pre-processing one or more obtained volumetric data sets and/or derivatives thereof in accordance with said position and/or orientation informative data; volume visualization processing one or more obtained volumetric data sets and/or derivatives thereof in accordance with results of pre-processing. | 02-05-2009 |
| 20090135045 | THROUGH-THE-OBSTACLE RADAR SYSTEM AND METHOD OF OPERATION - There are provided a through-the-obstacle radar system and method of operating thereof comprising recording signals and/or derivatives thereof collected during a certain substantial monitoring period, and using the recorded information for generating patterns informative of a monitoring scene. There are further provided a method of motion detection based on through-the-obstacle radar and the system thereof. The method comprises collecting signals and/or derivatives thereof acquired by the radar system during a certain substantial monitoring period and accommodating respective records, said records comprising information characterizing the signals and/or derivatives thereof and information indicative, at least, of the time the signals were obtained; processing the accommodated records and generating at least one histogram characterizing a normative motion level at different time intervals; comparing an actual motion level with the level in the normative histogram corresponding to the same time intervals; and recording the motion as detected if its actual level fits a certain relationship with the corresponding level in the normative histogram. | 05-28-2009 |
| 20090201195 | SIGNAL ACQUISITION AND METHOD FOR ULTRA-WIDEBAND (UWB) RADAR - An acquisition channel ( | 08-13-2009 |
| 20090243916 | SYSTEM AND METHOD FOR VOLUME VISUALIZATION IN ULTRA-WIDEBAND RADAR - Herewith disclosed a method for volume visualization in ultra-wideband radar and a system thereof. The method comprises perceiving processing provided in order to facilitate a meaningful representation and/or an instant understanding of the image to be displayed, said perceiving processing resulted in generating one or more perceiving image ingredients. The perceiving image ingredient may be, for example, a shadow added to the reconstructed image, a position-dependent color scheme applied to the reconstructed image, a color scheme adapted to external lighting conditions and applied to the reconstructed image, a Halo artificially added to the reconstructed image, a distinctive color scheme applied to time-invariant and time-variant elements of the reconstructed image, etc. | 10-01-2009 |
| 20090295618 | Through-Wall Imaging Device - A through-wall imaging device having antenna elements for transmitting and receiving signals adapted to pass through a wall for imaging objects therebehind, having a base with a carrier portion and a plurality of spaced-apart extensions connected thereto. At least a portion of the antenna elements are mounted on the extensions. The area between adjacent extensions is free of any material of the base at least when the extensions are in an operative state. | 12-03-2009 |
