Code 16.2: The NSCAT1 Geophysical Model Function

Code Name: NSCAT1.m

Description: Code computes Ku-band vv or hh σ0 for a specified incidence angle, radar azimuth angle, wind direction, wind speed, and polarization according to the NSCAT1 geophysical model function.

Input Variables:

  θ:    Incidence angle [15 ≤ θ ≤ 60] (degrees)
  ϕradar:    Radar illumination azimuth angle relative to north (deg)
  ϕwind:    Wind direction relative to north (meteorological convention, deg)
  U:    Wind speed [1≤ U≤30] (m/s)
  p:    polarization flag (hh: p = 1; vv: p = 2)

Output Products:

        σ0:    normalized radar cross-section (unitless)
