摘　　要：依据SUBSET-085标准,提出一种基于二次拟合的应答器谐振频率测试方法。该方法通过测试系统对应答器进行下行信号发送和上行信号接收的测试,并对上下行信号进行拟合计算,最终得出应答器的谐振频率。经验证,通过该测试方法进行谐振频率调整的应答器在标准测试环境下能量利用率更大,在SUBSET-085的I/O测试时性能表现更好。According to SUBSET-085 standard,this paper proposes a balise resonant frequency test method based on quadratic fitting.The method tests downlink signal transmission and uplink signal receiving of balise through testing system,and performs fitting calculation on uplink and downlink signal,and obtains resonant frequency of the balise finally.After verification,the resonant frequency of the balise which is adjusted by this test method has greater energy utilization rate,and which is performed better during the I/O test of SUBSET-085.
