THE PRINCIPLE OF GENERALIZED DIGISONDE DRIFT ANALYSIS
-
摘要: 本文给出一种广义Digisonde漂移分析(GDDA),取消了DDA的假设限制,使Digisonde漂移测量能应用于更为复杂的运动形式,如电离层研究中的剪切、辐散或辐辏等运动形式。文中阐述了GDDA的原理并给出一些模拟实验结果。

Abstract: he utility of Digisonde Drift Analysis(DDA)is demonstrated recently in the polar region ionospheric convection measurements. However, the assumption of uniform velocity in the field of view of sounder made in DDAis not always correct. Therefore a Generalized Digisonde Drift Analysis(GDDA)is introduced that is not limited to the condition of uniform velocity and thus makes it possible that the Digisonde drift measurement can be used in the complicated ionospheric motion analysis such as velocity shears, divergence and convergence. The main concept of GDDAand some promising simulation results are presented in the paper.
