摘要
本文针对太阳射电高时间分辨率观测研究中普遍关心的事件证认问题，分析了精细结构事件与干扰信号在“空域”和“频域”上的特征差异，在“１０ｃｍ波段高时间分辨率太阳强度纹”上，采取了抗干扰和识别干扰的技术措施，极大的抑制了雷达干扰，提高了事件的置信度。在缺乏不同地域精细结构同时性事件情况下，本文介绍的措施，对事件的自证认不失为一种有效的手段。
The problem widely concerned in the solar radio high time resolution observations is the identification of fine structure events.In this paper,we analyzed the character difference between the fine structure event and the interference signal for both 'spacefield' and 'frequency-field'. Based on our invesfigation,we adopted some methods of anti-interference and discerned the interference for the solar radio telescope with high time resolution at 10cm wavelength. Due to these methods,the radar interference may be suppressed grectly,and the reliability of the fine structure events improved.The method introduced in this paper, after all is an effective means for selfdiscrimination of the fine structure event without reference to the simultaneous events of the fine structure at different location.
