Abstract

Et oppadgående bølgefelt og et nedadgående bølgefelt beregnes ved en sensorposisjon fra et trykksensorsignal og et partikkelbevegelsessensorsignal (43, 44). Deretter beregnes et oppadgående bølgefelt ved en havbunnsposisjon i hovedsak uten havbunnsmultipler, fra de oppadgående og nedadgående bølgefeltene ved sensorposisjonen. I en utførelse propageres det oppadgående bølgefeltet ved sensorposisjonen bakover til havbunnen, noe som resulterer i et oppadgående bølgefelt ved havbunnen (45). Det nedadgående bølgefeltet ved sensorposisjonen propageres forover til havbunnen, noe som resulterer i et nedadgående bølgefelt ved havbunnen (46). Det oppadgående bølgefeltet ved havbunnen uten havbunnsmultipler, beregnes fra de bakoverpropagerte, oppadgående bølgefeltet ved havbunnen, og det foroverpropagerte, nedadgående bølgefeltet ved havbunnen, og en refleksjonskoeffisient ved havbunnen (48).
