9 November 1978 Aircraft Velocity And Altitude Measurements Using A Tunable Diode Laser
Author Affiliations +
A technique is proposed here for the on-board measurement of an aircraft's speed and altitude by measuring the doppler shift and linewidth of laser radiation which is resonantly scattered from carbon dioxide molecules in the air. The system employs a small, low power, tunable laser diode which gives a small, lightweight system with low power consumption. The technique promises to work very well at high altitudes (100,000 ft) and speeds (Mach 10).
