Trajectory Measurement Of Missile Cast Test In Proving Ground

The sub-munitions-warfare is a kind of exactitude armament. Taking full advantage of mature technology and pre-research work, the investigation and application of sub-munitions-warfare is possible at the present and suitable to our country's missile in current use. The research and produce of sub-munitions-warfare will significantly develop the campaign ability and efficiency of face-to-face missile. Therefore it is of great significance to impel the development of exactitude armament. aim at"the test of missile cast in proving ground", development and integration of measure system for the measurement of the trajectory of missile was finished. The ballistic trajectory could be calculated exactly by analyzing the image sequence. Results attained in this paper are as follows.1) Design and integration of the measure system was completed, including the design and machining of the measure system platform, the integration of the whole hardware system and the calibration of the system.2) The position of the missile was exactly acquired by dealing with the image sequence. The experiment data curve and result analysis were presented.3) Image sequence was dealing with difference-maps method. The feasibility and practicability of this method were proved by analyzing the result data.4) Both correlation arithmetic and difference-maps method were used in experimental results analysis. Comparison of these two methods was completed by comparing the displacement curve and the velocity curve. Strongpoint and demerit of each method were concluded.
