本文报告了 SELENE (KAGUYA) 任务期间飞行自旋卫星上天线相位图的测量结果，并首次清晰地显示了每月的变化。当天线加载在自旋卫星上时，由于天线相位图的影响，会出现具有自旋频率和高阶谐波的周期性分量并影响多普勒测量。由于SELENE的两颗子卫星Rstar和Vstar具有八角棱柱体，因此在2路和4路多普勒数据中，8次、16次和24次谐波相对较强。这三个谐波的振幅在超过一年的整个任务中明显变化，周期为 27.32 天（一个恒星月）。天线相位图是使用1-26次谐波估计的，其均方根变化的周期也是27.32天。根据 24 次谐波和天线相位图，可以估计整个任务期间 Rstar 和 Vstar 的自旋频率变化，精度为 Hz。
This paper reports measurement results of the antenna phase patterns onboard flying spin satellites during the SELENE (KAGUYA) mission period, and shows monthly variations clearly for the first time. When an antenna is loaded on a spin satellite, due to the effects of the antenna phase patterns, periodical components with the spin frequency and higher order harmonics occur and influence Doppler measurements. Because Rstar and Vstar, two subsatellites of SELENE, have octagonal prismatic bodies, the 8th, 16th, and 24th harmonics are relatively stronger than the other ones in the 2-way and 4-way Doppler data. These three harmonics' amplitudes over the entire mission longer than one year clearly varied with a period of 27.32 days (one sidereal month). The antenna phase patterns were estimated using 1-26th harmonics, whose rms variations were also with a period of 27.32 days. From the 24th harmonic and the antenna phase patterns, the spin frequency variations of Rstar and Vstar over the entire mission were estimated with an accuracy of Hz.
