################################### ##### ANTENNA INFORMATION ##### ################################### ################################### # ANTENNA INFO VECTOR SIZE ################################### # The number of antenna info # structures in the vector. Each # entry in this vector is a structure # with the following elements: # # - CARRIER_FREQUENCY # - PC_OFFSET # - PC_VARIATION_CORRECTION # - PC_VARIATION_CORRECTION_UNC # - SIGNAL_GAIN_CORRECTION # - SIGNAL_GAIN_CORRECTION_UNC # # Notes: # CARRIER_FREQUENCY # The carrier frequency in MHz. # # PC = PHASE CENTER # PC_OFFSET is a structure with six # elements: x, y, z and their associated uncertainties # Phase center offset (PCO) is defined with # respect to the origin of the Android sensor coordinate system, e.g., # center of primary screen for mobiles # # PC_VARIATION_CORRECTION # 2D vectors representing the phase center variation (PCV) corrections, # in millimeters, at regularly spaced azimuthal angle (theta) and zenith angle # (phi). The PCV correction is added to the phase measurement to obtain the # corrected value. # The azimuthal angle, theta, is defined with respect to the X axis of the # Android sensor coordinate system, increasing toward the Y axis. The zenith # angle, phi, is defined with respect to the Z axis of the Android Sensor # coordinate system, increasing toward the X-Y plane. # Each row vector (outer vectors) represents a fixed theta. The first row # corresponds to a theta angle of 0 degrees. The last row corresponds to a # theta angle of (360 - deltaTheta) degrees, where deltaTheta is the regular # spacing between azimuthal angles, i.e., deltaTheta = 360 / (number of rows). # The columns (inner vectors) represent fixed zenith angles, beginning at 0 # degrees and ending at 180 degrees. They are separated by deltaPhi, the regular # spacing between zenith angles, i.e., deltaPhi = 180 / (number of columns - 1). # # PC_VARIATION_CORRECTION_UNC # 2D vectors of 1-sigma uncertainty in millimeters associated with the PCV # correction values. # # SIGNAL_GAIN_CORRECTION # 2D vectors representing the signal gain corrections at regularly spaced # azimuthal angle (theta) and zenith angle (phi). The values are calculated or # measured at the antenna feed point without considering the radio and receiver # noise figure and path loss contribution, in dBi, i.e., decibel over isotropic # antenna with the same total power. The signal gain correction is added the # signal gain measurement to obtain the corrected value. # The azimuthal angle, theta, is defined with respect to the X axis of the # Android sensor coordinate system, increasing toward the Y axis. The zenith # angle, phi, is defined with respect to the Z axis of the Android Sensor # coordinate system, increasing toward the X-Y plane. # Each row vector (outer vectors) represents a fixed theta. The first row # corresponds to a theta angle of 0 degrees. The last row corresponds to a # theta angle of (360 - deltaTheta) degrees, where deltaTheta is the regular # spacing between azimuthal angles, i.e., deltaTheta = 360 / (number of rows). # The columns (inner vectors) represent fixed zenith angles, beginning at 0 # degrees and ending at 180 degrees.
