Hf Coastal Current Mapping Radar System
US Patent:
4172255, Oct 23, 1979
Filed:
Aug 8, 1977
Appl. No.:
5/822868

Abstract:
A system for radar remote sensing of near surface ocean currents in coastal regions. The system employs a pair of low power, transportable high frequency radar units to scatter signals from the shore off to the ocean waves. Underlying surface currents impart a slight change in velocity to the ocean waves which is detected by the radar units. Each radar unit can determine the angular direction of arrival of the radar echo signals by comparing the phase of the signals received at three short antennas on the shore. Signals scattered from the same point on the ocean by each of the two geographically separated radar units are used to construct a complete current vector for that point. The radar pair takes simultaneous measurements over an ocean area with a predetermined grid pattern. Vectors are constructed for each square section of the grid, and a map of the near surface current field is output in real-time by an on-site minicomputer.

International Classification:
H05K 720
US Classification:
361384
Abstract:
A power supply system is enclosed in a housing. A disk drive receptacle is arranged in the front of the housing, and a power supply and card cage for the microcomputer are laterally arranged at the rear of the housing. The front and rear of the housing are air permeable for cooling air. A power supply control circuit, for control of the power supply, controls a solid state relay in series with the power input to the power supply. The power supply control circuit also generates control signals, indicating pending power failure, for the microcomputer arranged in the card cage.
