Title: The Innovative Contributions of Leon Green

Introduction

Leon Green is a notable inventor based in Newton, MA (US), recognized for his significant contributions to radar technology. With a total of 7 patents, Green has made strides in the field of phased array antennas and active array radar systems. His work has been influential in advancing radar systems used in various applications.

Latest Patents

Among his latest patents, Green has developed a phased array antenna that utilizes stacked beams in both elevation and azimuth. This radar system features a rotating antenna array with rows that exhibit dispersive properties while feeding multiple radiating elements. In certain embodiments, the radiating elements are dual polarized, and beam spoiling techniques may be employed to create an unfocused transmit beam that covers an entire elevation range of interest. Additionally, digital beam forming is utilized during the receive mode to achieve a stack of narrow-width receive beams in elevation, while frequency scanning is applied to achieve stacked beams in azimuth.

Another significant patent by Green is the photonically controlled active array radar system. This innovative system is managed by photonic signals and consists of an array of N antenna elements divided into M subarrays. Each subarray contains N/M antenna elements, and tunable lasers provide M optical wavelengths within non-overlapping bands. The microwave transmit pulse is amplitude modulated onto the M optical signals, with time delays introduced for offsets between elements in a subarray and between subarrays. This design allows each antenna element to have a true time delay through wavelength division multiplexing.
