METHOD OF MEASUREMENT OF HEIGHT OF SEA WAVES FROM FLYING VEHICLE ON FLOAT Russian patent published in 1998 - IPC

FIELD: noncontact oceanographic measurements. SUBSTANCE: measurement of height of sea wave from flying vehicle on float is conducted by means of receiving-radiating system and accelerometer finding distance to sea surface. Signals corresponding to distances to sea surface are filtered by filter with transfer function K(p) which bandwidth includes spectrum of oscillations of sea surface, signals of accelerometer are filtered by filter with transfer function K(p), where p is complex frequency. Signals proportional to oscillations of sea surface are obtained after subtraction of signals of both filters. After their analysis one finds height of sea waves. EFFECT: increased measurement accuracy with processing of results at pace of information coming. 1 dwg
