二维微重力测量与目标发现率研究

随着测量仪器精度的提高,重力勘探正逐步走向微重力勘探阶段。与普通的重力测量相比,微重力测量虽然获得数据精度较高,探测到比较微弱的重力异常,但也容易受测量条件等可控因素的影响,降低了对异常体的发现率。以简单规则球体为理论模型,分别对影响目标体发现率的仪器因素、目标球体的模型因素、航空测量等因素作了初步研究。定性地给出了目标体发现率与各种影响因素之间的关系。并以理论模型模拟实测数据,体现出正确处理可控制因素对于实际工作的影响。

Two-dimensional Microgravity Measurement and Target Detection Rate

Along with the measurement instrument accuracy,low gravity prospecting gradually becomes the exploration stage.Compared with the normal gravity measurement,the measurement data obtained though microgravity compared with high precision and detect weak gravity anomaly.But also vulnerable to measuring conditions controllable factors,reduced the rate of abnormal body.Based on the simple rules for theoretical model,sphere of influence of the instruments that rate target body,the model of target sphere rolling te...
