A Fiber-Optic-Based 1550-nm Laser Radar Altimeter with RF Pulse Compression

  title={A Fiber-Optic-Based 1550-nm Laser Radar Altimeter with RF Pulse Compression},
  author={Christopher and Allen and Sivaprasad and Gogineni},
-We are developing a laser radar (lidar) altimeter that uses commercial off-the-shelf fiber-optic components and traditional RF and digital signal processing techniques to achieve fine-range accuracy despite a low transmit peak power. A 1550-nm operating wavelength was selected so that available erbium-doped fiber amplifiers (EDFAs) could be used to provide optical gain. The transmitted signal, an amplified, gated CW optical carrier intensity modulated with a linear-FM (chirp) RF signal, is… CONTINUE READING
