Calculate an incoherent scatter spectrum with arbitrary isotropic electron velocity distributions and radar pointing at oblique angles to the magnetic field
Project description
INcoherent SCAtter Radar spectrum
Info
Calculates an incoherent scatter radar spectrum based on the theory presented in Hagfors (1961) and Mace (2003).
Installing
You can install inscar via pip from PyPI:
$ pip install inscarUsage
Please see the Modules Reference for details.
Numba
Faster integration is accomplished by computing in parallel. This is accomplished using numba.
Physical environment
The available plasma parameters that can be changed within the program are
=== Input parameters ===
K_RADAR -- Radar wavenumber (= -4pi(radar frequency)/(speed of light)) [m^(-1)]
B -- Magnetic field strength [T]
MI -- Ion mass in atomic mass units [u]
NE -- Electron number density [m^(-3)]
NU_E -- Electron collision frequency [Hz]
NU_I -- Ion collision frequency [Hz]
T_E -- Electron temperature [K]
T_I -- Ion temperature [K]
T_ES -- Temperature of suprathermal electrons in the gauss_shell VDF [K] (no longer in use)
THETA -- Aspect angle [1]
Z -- Height used for calculated distribution [100, 599] [km]
mat_file -- Time of day for calculated distribution
pitch_angle -- Pitch angle for calculated distributionCalculation method
The program support different methods of calculating the spectrum, based on how you assume the particles to be distributed. This includes a Maxwellian distribution and a kappa distribution, in addition to any arbitrary isotropic distribution.
