Error analysis of single station passive location in high-frequency based on the circular error probable

The circular error probable is extensively used to evaluate the performance of passive location system.With the aid of the single station passive location model in high-frequency, the circular error probable is obtained, which concerning the errors of azimuth, elevation and ionosphere virtual height.Since traditional circular error probable just provides the approximate formula with probability near 50%, the new error formulae is calculates by arbitrariness probability.The simulation shows that the relative error of the theoretical result is less than 1% compared with the experiment result which validates the correctness of theoretical method.
