The ways to investigate discontinuous character which is significant to stealth aircraft design on surface are divided into numerical computation and experiment, both of them have disadvantages such as low precision for numerical computation and high cost for experiment. A new numerical method named as half-measurement method (HMM) basing on simple experimental data is developed to estimate the more complex discontinuous characters, it is shown that half-measurement method has a high calculation precision.
