摘　　要：为了提高罗兰-C磁天线的接收能力,设计了一种顺接串联多层线圈的磁天线。理论推导了顺接串联多层线圈磁天线的信噪比和灵敏度,最终设计的磁天线大小为150 mm×150 mm。远场测试接收到了较高信噪比的罗兰-C信号,在相同信号调理电路条件下,与单层单组线圈的磁天线相比,顺接串联多层线圈的磁天线接收到3.47 V的电压信号,且信噪比高达30.87 dB,灵敏度和信噪比分别提高了82.42%和63.20%。顺接串联多层线圈磁天线提高了罗兰-C磁天线的灵敏度和信噪比,对罗兰-C系统在定位方面的应用具有重要意义。A kind of magnetic antenna with order series multi-layer coils is made for improving the receiving ability of the Loran-C magnetic antenna.The signal-to-noise ratio and sensitivity of order series multi-layer coil magnetic antenna are derived theoretically.Final designed magnetic antenna size is 150 mm×150 mm.It can receive the completed and clear Loran-C signal in far-field test.Under the same signal conditioning circuit conditions,compared with single layer and single group of coils magnetic antenna,order series multi-layer coils magnetic antenna receives a voltage signal of 3.47 V,and the signal-to-noise ratio is 30.87 dB.The sensitivity and signal-to-noise ratio are improved 82.42%and 63.20%respectively.The proposed method improves the receiving performance of the Loran-C magnetic antenna,which is of great significance to the application of the Loran-C system in positioning.
