Latest Patents

Two of his most recent patents highlight his pioneering work:

1. **Radar Microphone Speech Recognition**: This method provides a novel approach to detecting and recognizing speech remotely. By utilizing radar sensors that transmit distinct waveforms towards the speaker, the system captures body motions during vocalization. The received scattered radio frequency energy is analyzed using digital signal processors, allowing the extraction of Doppler signals related to vocalization. Ultimately, words are recognized through a sophisticated word classifier that interprets these feature vectors.

2. **Determination of Jammer Range and Azimuth**: In this patent, Hansen designed an advanced countermeasure detection system aimed at evaluating the range and direction of noise jammers in radar environments. The invention employs a signal limiter within a multi-loop side-lobe canceller system, focusing only on interference within the main lobe. By calculating the absolute phase of interference signals at auxiliary antennas and leveraging known placements, the system can effectively determine the range and azimuth of a jammer using available processing equipment.
