Progress towards a “FLASH” imaging RADAR using RF photonics

Abstract

Herein, a novel approach to realizing an imaging millimeter-wave RADAR is presented. Time gated sampling based on both laser source modulation and high speed photodiodes are being explored. Additionally, methods for fabricating densely packed optical upoconversion arrays have been demonstrated based on liquid crystal polymer technology that will be described in more detail. These techniques should enable a new class of imaging RADARs suitable for short range applications where high resolution is required such as degraded visual environment mitigation sensors.
