摘要

Requirements for an air data system for future aircraft has been specified. The requirements includes advanced maneuvering of the aircraft at up to a height of 20 km. Different potentially useful laser based measurement methods are discussed. Based on the requirements, the characteristics of the different methods and their technical maturity, the conclusion is that a pulsed coherent laser radar system (pulsed CLR-system) should be best suited for the function as an optical air data system (OADS). The signal to noise ratio (SNR) has been calculated for a realistic OAD-system. SNR is an important system parameter which affects both the accuracy and the update rate of the measurements. The expected measurement uncertainty for the radial velocity is also discussed.
