Lidar Manipulation Hardware
REQUIREMENT
The Geospatial Research Laboratory (GRL) requires a suite of advanced electronic equipment capable of precise and low-noise signal acquisition, measurement, and generation. The GRL requires devices that can reliably capture and analyze subtle variations in signals, as well as generate highly stable and accurate waveforms. This is critical for research, which demands minimal interference and maximum fidelity in signal processing. These electronics performance needs to meet certain specifications provided in below table. The subject matter experts at GRL conducted performance link budget to come up with the specifications and requirements for these electronics.
System Requirements: Table 1, 2, 3, 4, and 5 provide the list of required items and the key specifications to be satisfied.
