pyrad.proc.process_rcs_pr#

pyrad.proc.process_rcs_pr(procstatus, dscfg, radar_list=None)[source]#

Computes the radar cross-section (assuming a point target) from radar reflectivity by first computing the received power and then the RCS from it.

Parameters:

procstatus (int) – Processing status: 0 initializing, 1 processing volume, 2 post-processing

dscfg (dictionary of dictionaries) –

data set configuration. Accepted Configuration Keywords:

datatype : list of string. Dataset keyword
    The input data types, must contain,
    "dBZ" or "dBuZ" or "dBZc" or "dBuZc" or "dBZv" or "dBuZv" or "dBuZvc"
AntennaGainH, AntennaGainV : float. Dataset keyword
    The horizontal (vertical) polarization antenna gain [dB]. If None
    it will be obtained from the attribute instrument_parameters of
    the radar object
txpwrh, txpwrv : float. Dataset keyword
    The transmitted power of the horizontal (vertical) channel [dBm].
    If None it will be obtained from the attribute radar_calibration
    of the radar object
mflossh, mflossv : float. Dataset keyword
    The matching filter losses of the horizontal (vertical) channel
    [dB]. If None it will be obtained from the attribute
    radar_calibration of the radar object. Defaults to 0
radconsth, radconstv : float. Dataset keyword
    The horizontal (vertical) channel radar constant. If None it will
    be obtained from the attribute radar_calibration of the radar
    object
lrxh, lrxv : float. Global keyword
    The horizontal (vertical) receiver losses from the antenna feed to
    the reference point. [dB] positive value. Default 0
ltxh, ltxv : float. Global keyword
    The horizontal (vertical) transmitter losses from the output of the
    high power amplifier to the antenna feed. [dB] positive value.
    Default 0
lradomeh, lradomev : float. Global keyword
    The 1-way dry radome horizontal (vertical) channel losses.
    [dB] positive value. Default 0.
attg : float. Dataset keyword
    The gas attenuation [dB/km]. If none it will be obtained from the
    attribute radar_calibration of the radar object or assigned
    according to the radar frequency. Defaults to 0.
radar_list : list of Radar objects
    Optional. list of radar objects

Returns:

new_dataset (dict) – dictionary containing the output field “rcs_h” or “rcs_v” (if vert. refl. were provided)
ind_rad (int) – radar index
