I Shaun Carnes, Deceased

Title: I Shaun Carnes and His Contributions to CW Radar Technology.

Introduction

I Shaun Carnes was an inventor associated with Chelmsford, Massachusetts, and Raytheon Company. His patent work focused on continuous-wave (CW) radar systems for measuring target range and Doppler frequency. He held 2 patents related to this technology.

Latest Patents

Carnes’s listed patents are “CW Radar Range Measuring System with Improved Range Resolution” and “CW Radar Range Measuring System.” Both describe a system that transmits a continuous-wave radar signal encoded according to a code and processes the returning signal to estimate a target’s range.

The system converts radar-return samples into digital words and uses a digital correlator and integrator to assess return energy across ranges. A processor uses that information to determine target range, while frequency-spectrum analysis supports the determination of target Doppler frequency. The improved-range-resolution patent also describes determining range with accuracy finer than the time interval associated with the phase-encoding rate.

Career Highlights

Carnes’s patents document work on digital signal processing for CW radar, combining coded transmissions, correlation, integration, and frequency analysis. The described system allows range and Doppler information to be derived from radar returns.

Collaborations

Carnes was associated with Raytheon Company. His listed coworkers include Dean L. Shollenberger and David A. Marquis.

Conclusion

I Shaun Carnes’s two listed patents reflect contributions to CW radar measurement, particularly the processing of radar returns to determine target range and Doppler frequency.
