| 摘 要： | 为实现高能宇宙线射电探测方法，对射电探测法的关键技术一接收天线展开了研究。在综合分析宇宙线大气簇射信号特性的基础上，提出了一套新的宽频分段天线接收方案：即在较低频段采用底部加载有源低频天线接收射电信号，而在较高的甚高频频段采用对数周期天线接收射电信号。经仿真和预研究实验证明本设计方案可用于高能宇宙线的射电探测。

| Abstract: | In order to achieve the radio detection method of high-energy cosmic ray,antenna study which was the key technology of radio detection method was carried out.According to analyzing the characteristics of high-energy cosmic ray,a new set of receiving plan was proposed,which was composed by two broad-band antennas: base-loaded active antenna was adopted in low frequency band,and log periodic dipole array(LPDA) was adopted in VHF.Both the pre-research experiment and emulations illustrate that the design could ... |
