Abstract
Technologies for temperature gain control on radar units are described. A method includes determining a first value for an internal operating temperature corresponding to a steady-state of a radar unit. The method further includes causing the radar unit to operate in a first mode that heats the radar unit. The method further includes obtaining a second value for the internal operating temperature at a first time in the first mode and determining a third value indicating a measurement bias associated with the radar unit. The method further includes determining a fourth value using the second value and the third value. The fourth value indicates an updated internal operating temperature of the radar unit. The method further includes determining that the fourth value satisfies a threshold temperature condition corresponding to the first value. The method further includes causing the radar unit to stop operating in the first mode.
