METHOD FOR DETERMINING THE COURSE aerodynamic targets

摘要

A method of determining the course aerodynamic purposes, comprising the steps that produce the transformation of the measured spherical coordinates in a horizontal Cartesian coordinates are evaluated rate of change of the horizontal cartesian coordinates evaluated auxiliary angle between the velocity vectors change horizontal Cartesian coordinates as the arctangent of the quotient of velocity estimates the changes of the horizontal cartesian coordinates, course objectives wind is uniquely determined by the following algorithm, if the estimate is STI change horizontal cartesian coordinates is greater than zero, the rate is equal to the estimate of the auxiliary angle, if the speed estimate the change of the horizontal cartesian coordinate is less than zero, then the rate equal to the difference between the estimate of the auxiliary angle and an angle of 180 °, if the estimated rate of change of the horizontal cartesian coordinates on the coordinate axis, the positive direction which is the origin of measurement of azimuth and course, greater than zero, and the estimation speed change other horizontal cartesian coordinates is less than zero, then ku pc is the difference between 360 ° and evaluation auxiliary angle if the estimate of the rate change horizontal Cartesian coordinates on a coordinate axis, the positive direction which is the origin of measurement of azimuth and course is less than zero, and the estimation speed change other horizontal cartesian coordinates is greater than zero, then the rate equals the sum of evaluations of the auxiliary angle and the angle of 180 °, characterized in that the coordinate transformation is calculated on the product of the radial velocity-range, the sample obtained produ
