Latest Patents

One of his latest patents is the "Wideband co-site interference reduction apparatus." This invention presents an interference cancellation system designed to improve the rejection of signals coupled from a transmission antenna into a local receive antenna amidst local multipath conditions. The system incorporates a frequency hopped radio that operates effectively in a dispersion environment. It features an instantaneously limited bandwidth communication channel that spans a substantially larger bandwidth. The transmission of signals is facilitated through a directly coupled reference path and a received coupled path. A delay mechanism is employed to variably adjust the phase slope delay of the signal in one path relative to the other. Additionally, an amplitude slope means is utilized to variably adjust the amplitude slope of the signal in each path. A digital controlling means enhances the performance of the co-site interference reduction system by providing improved matching of the signals.

Another significant patent is the "Adaptive main beam nulling using array antenna auxiliary patterns." This invention allows for automatic reduction of jamming or other interference affecting radar or Identification Friend or Foe (IFF) systems without the need for separate auxiliary antennas. The primary beam forming network employs four-port directional coupler devices, which utilize ancillary ports that would have been resistively terminated otherwise. Signals from these ancillary ports are coupled to an auxiliary beam forming network to create auxiliary beam patterns that are orthogonal to and track the steered main beam patterns. The system employs least mean square (LMS) control loops that operate on a feedback basis to derive weighted auxiliary signals responsive to jamming signals. These weighted auxiliary signals are then combined with the primary received signals in reverse polarity to effectively nullify the jamming signals.
