Study on gain calibration method of CSRH
摘要
Abstract
In this paper,a Y factor method is proposed for the gain calibration experiment of LF array antenna on CSRH, whose basic approach and framework are introduced in detail. The UV coverage diagrams of CSRH-I and CSRH-Ⅱare given. The gain of CSRH-I was tested and calibrated by taking quiet sun as calibration source and using the method of calibration source test. The preliminary results are offered. The feasibility and calibration error are analyzed with the relative data.关键词
