Direct orthogonal signal correction(DOSC) and Savitzky-Golay filters (SGF) were applied as preprocessing methods on the original and first derivative absorbance data. Principle component regression (PCR), partial least squares (PLS) and iterative target transformation factor analysis (ITTFA), were used in spectrophotometric simultaneous determination of heavy divalent metal ions, l...
Adaptive optics is implemented in a harmonic generation microscope using a wavefront sensorless correction scheme. Both the second- and third-harmonic intensity signals are used as the optimization metric. Aberration correction is performed to compensate both system- and specimen-induced aberrations by using an efficient optimization routine based upon Zernike polynomial modes. Images of live m...
The method of mutual coupling correction of array output signal is studied in the paper. According to array signal processing’s feature, array error model is analyzed and array mutual coupling is studied. The method that smart antennas’ channel calibration by BP network in wireless communication is proposed, which improves the accuracy of algorithms , such as the DOA estimation algorithm, Beam ...
The signal recorded by the sensor contains information relative both to the atmosphere and the surface. Atmospheric correction is necessary to extract the surface reflectance required within biophysical algorithms used to estimate canopy characteristics. Aerosol characteristics are the most difficult to evaluate because they vary rapidly with time and space. The objective is to develop an auton...
