| 摘 要： | 基于重力场的频谱理论，给出了扰动引力在全球平均意义下的功率谱表达式，揭示了扰动引力的传播特性。通过数值试验，给出了扰动引力随高度变化规律，并分析了不同高度上，扰动引力恢复重力场的最高阶数及相应分辨率。从理论上分析了航空重力测量探测重力场中高频信息的能力，对制定飞行方案有一定参考价值。

| Abstract: | The paper presents the power spectral expression in terms of global mean disturbing gravity as well as its propagation features based on the spectral analysis theory of the gravity field.The characteristic of the variation of the disturbing gravity with height is proposed through numerical experiments,and the max degree of the gravity field recovery as well as respective resolution is analyzed.A theoretical research is made on the capability of the detection of middle and high frequency information of the gravity field using airborne gravimeter,and thus it can be helpful in making a flight scheme. |
