| 摘 要： | 针对三频信标高精度探测的特点,开展了部分比较和模拟工作,结果表明采用三频信标获得的TEC精度高于双频信标。电离层CIT成像的结果显示,采用三频信标能够探测出较小尺度的电离层扰动,而双频信标对小尺度扰动的探测结果往往无能为力。

| Abstract: | Tri-band beacon has the characteristic of high precision detection.Comparisons and numerical simulations between tri-band beacon and two-frequency beacon were carried out.The results showed TEC derived by three-frequency are much better than those by two-frequency method.The computerized ionospheric tomography demonstrated that smaller scale ionosphere perturbations can be measured using tri-band beacon while the two-frequency beacon cannot do that. |
