Abstract: A method includes receiving wavelength domain data for a time step, performing a Discrete Fourier Transform (DFT) to transform the wavelength domain data for the time step into frequency domain data for the time step only for the limited set of frequency bins associated with a frequency of interest, calculating pressure based on the frequency domain data for the time step, and updating the frequency of interest and the limited set of frequency bins. The method includes repeating receiving wavelength data for subsequent time steps, performing a DFT to transform the wavelength data for the respective subsequent time steps, calculating pressure for each subsequent time step, and updating the frequency of interest and limited set of frequency bins for each subsequent time step. The method includes outputting pressure data based on calculating pressure for the subsequent time steps.

Abstract: An aircraft includes an air data sensor and a heating element. The air data sensor includes a probe and transducer coupled to the probe. The heating element is disposed within the probe and is configured to emit heat that heats the probe. The aircraft further comprises a heater control system in signal communication with the heating element and a thermal sensor system. The thermal sensor system is configured to determine the emitted heat from the heating element based on the thermal radiation of heat released from a surface of the probe. In this manner, the heater control system can actively vary the temperature of the heating element based on the emitted heat from the heating element.
