Abstract

Systems and methods for laser based measurement of air parameters for use, e.g., on aircraft are disclosed. An example system includes a coherent source of radiation, a modulator, a transceiver, an optical mixer, and a measuring system. The coherent source produces a coherent radiation beam, and the modulator is configured to modulate the coherent radiation beam. The transceiver is configured to transmit the modulated radiation beam to, and receive a scattered radiation signal from a target region. The optical mixer is configured to determine a difference between the scattered radiation signal and the reference radiation beam. The measuring system is configured to determine at least one of velocity, air density, pressure, temperature, barometric altitude, angle of attack, angle of side slip, icing and turbulence based on the difference between the scattered radiation signal and the reference radiation beam.
