Spatial multibeam ambiguity resolving technique (SMART) |
May 3, 2005 |
| A synthetic aperture radar (SAR) image of a wide coverage area is acquired during a frame containing a first plurality of ambiguities induced in the SAR image from radar scatterers within the area. The area is illuminated with radar pulses and a segmented receive antenna oriented towards |

Phased array antenna system with virtual time delay beam steering |
March 4, 2003 |
| A system and technique for phased array antenna beam steering for transmitting and receiving without sending the waveform through an actual (physical) time delay when a time varying frequency is used as the waveform. The inventive system is adapted for use with an antenna having an a |

Method and apparatus for parallel high speed data transfer |
February 16, 1999 |
| The present invention concerns a method for eliminating or reducing clock skew introduced by differing signal propagation delays across a data bus. At high bus clock frequencies the time delay differences caused by path length differences can be catastrophic and must be eliminated by exp |
