Abstract

SEAHAWK is a high-performance, low-SWAP LIDAR for real-time topographic and bathymetric 3D mapping applications. Key attributes include real-time waveform and point cloud processing, real-time calculation of total propagated uncertainty (TPU), a novel co-located green and infra-red transceiver architecture based on a 12” circular scanner with holographic optical element (HOE), an ultra-compact Cassegrain telescope, custom detector architecture with dynamic load modulation (DLM), and analog-to-digital converters providing improved resolution, dynamic range, and sensitivity. SEAHAWK’s design yields higher sea-surface detection percentages than other circular scanning LIDARs and thereby enables more robust sea-surface correction strategies. The real time point clouds provide sensor operators with immediate, actionable intelligence about data quality while the aircraft remains on-station.
