Measures of length are always in meters except when describing antenna array elements.
With antenna arrays, units of length are in carrier wavelengths since an array’s behavior and characterization is its geometry relative to carrier wavelength. This convenience makes the antenna arrays in MFM agnostic to carrier wavelength—evidenced by the fact that antenna arrays in MFM are not informed of the carrier wavelength.
Measures of frequency and bandwidth are always in units Hertz.
Measures of time are always in units seconds.
Velocities are always in meters/second.
Azimuth and elevation angles are always in radians except when plotting (e.g., array patterns) since degrees are often easier to interpret.
Power quantities are always in Watts (except when specifying units otherwise).
Power spectral densities are always in Watts/Hz (except when specifying units otherwise).
Linear units are used throughout MFM rather than log-based units (e.g., dB) except on occasion when plotting.
Some gain values are in amplitude gain (e.g., a
link object’s large-scale gain) while other gain values are in linear power loss (e.g., a
path_loss object’s attenuation). Please refer to the documentation for clarification on a particular value.
