Title: The Innovative Contributions of James C Long in Radar Technology

Introduction

James C Long is a distinguished inventor based in Sunnyvale, California, who holds a remarkable seven patents in the field of radar technology. His inventive spirit and commitment to innovation have led to significant advancements, particularly in systems designed for concrete penetration and object detection.

Latest Patents

Among his latest inventions are two notable patents that showcase his ingenuity. The first is the **Dual Transmitter Visual Display System**, a cost-effective wideband radar system designed to locate objects such as reinforcing steel rods, pipes, and air bubbles embedded within concrete, soil, wood, or air. This sophisticated system emits a sequence of wideband radar pulses without a carrier from two transmit antennas. It features a receiver that detects reflected pulse energy—echoes that occur when transmitted pulses hit a change in material. The visual display illustrates the amplitudes of these echoes alongside the lengths of the transmit/echo paths for each transmitter, enabling users to ascertain the location of objects within solid volumes.

The second invention is the **Ultra Wide-band Radar Antenna for Concrete Penetration**. This innovative pyramidal horn antenna minimizes ringing in radar systems when it is applied against solid volumes like concrete or wood. It is engineered with a pyramid-shaped dielectric that features a rectangular base and four triangular sides converging at the apex. The design includes conductive triangular plates that connect to a radar system, providing an efficient impedance match between the antenna and the solid volume, thereby enhancing detection capabilities.

Career Highlights

James has made significant contributions to the companies he has worked with, including First Pacific Networks and Zircon Corporation. His expertise in radar technology has helped these organizations push the boundaries of what is possible in object detection.

Collaborations

During his career, James collaborated with notable colleagues such as Charles E Heger and Noel H Marshall. Together, they have driven forward innovative projects and patents that reflect their shared commitment to advancing radar technology.
