Abstract: A coherent Doppler lidar has been developed by NASA for providing vector velocity and altitude data to landing vehicles. Future robotic and manned missions to planetary bodies demand precise ground-relative velocity and altitude data to execute complex descent maneuvers for safe, soft and pinpoint landing at a pre-designated site.

Del, or nabla, is an operator used in mathematics (particularly in vector calculus) as a vector differential operator, usually represented by the nabla symbol ∇.

2025年3月7日 · Vectra’s NDR for Cloud (NDRC), provides a unique opportunity to provide greater abilities to capture network traffic throughout public cloud platforms. The purpose of this guide is to provide the reader with a clear understanding of the design and deployment best practices for component placement. Each Cloud environment, whether it be...

NDL Sensor System Description Figure 1 illustrates the NDL system design. The lidar uses a frequency modulated continuous wave (FMCW) technique and optical homodyne detection to obtain both range and velocity data. A relatively low power, single frequency laser operating at an eye safe wavelength of 1.55 microns is used as the master oscillator.
