Abstract

Šis išradimas priklauso ultragarsinių matavimų ir sistemų sričiai. Jame atskleidžiama: būdas, prietaisas ir sistema, skirti ultragarsu įvertinti augalų lapų (2) fiziologinį atsaką ir jo pokytį dėl aplinkos poveikių, pavyzdžiui, nusakyti augalo drėkinimo trūkumą. Skirtingai nei žinomi sprendimai, naudojantys vieną trumpą plačiajuosčio ultragarso impulsą, šiame išradime panaudoti skleisto spektro signalai, pavyzdžiui, pasirinktos pozicijos ir pločio impulsų skleisto spektro (APWP SS) UG signalai, dažniu moduliuotos („chirp“) arba kodinės sekos. Šie signalai leidžia pasiekti pakankamą matavimo SNR, ir įvertinti, ypač praktinio taikymo aplinkybėmis, fiziologines lapų (2) charakteristikas (tokias, kaip santykinis vandens potencialas RWC, turgoro praradimas ir slėgis, vandens potencialas). Išradimas sprendžia atvirkštinį uždavinį laiko srityje, kur ieškomas rezultatas yra lapo (2) modelio parametrų – storio, tankio, UG sklidimo greičio ir slopinimo – geriausias atitikimas užregistruotam lapo UG matavimo signalui. Išradimas leidžia patikimai matuoti lapų (2) atsaką lauko sąlygomis (pasižyminčiomis temperatūros, drėgmės, slėgio pokyčiais), todėl yra praktiškas naudoti žemės ūkio specialistams ir ūkininkams.
