摘要: 為了提高羅蘭-C磁天線的接收能力,,設(shè)計了一種順接串聯(lián)多層線圈的磁天線。理論推導(dǎo)了順接串聯(lián)多層線圈磁天線的信噪比和靈敏度,,最終設(shè)計的磁天線大小為150 mm×150 mm,。遠(yuǎn)場測試接收到了較高信噪比的羅蘭-C信號,在相同信號調(diào)理電路條件下,,與單層單組線圈的磁天線相比,,順接串聯(lián)多層線圈的磁天線接收到3.47 V的電壓信號,且信噪比高達30.87 dB,,靈敏度和信噪比分別提高了82.42%和63.20%,。順接串聯(lián)多層線圈磁天線提高了羅蘭-C磁天線的靈敏度和信噪比,對羅蘭-C系統(tǒng)在定位方面的應(yīng)用具有重要意義,。

Abstract: 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.
Key words : Loran-C,;magnetic antennas,;sensitivity;signal-to-noise ratio

0 引言

    羅蘭-C是一種陸基遠(yuǎn)程無線電導(dǎo)航系統(tǒng),,工作頻段為90~110 kHz[1-5],。磁天線相對于電天線具有體積小、靈敏度高,、抗干擾能力強[6]以及便于安裝和攜帶等優(yōu)點,,常被用來接收羅蘭-C信號。

    目前羅蘭-C磁天線的研究主要在方向性優(yōu)化[7],、數(shù)字移相算法[8]以及有源接收技術(shù)[9-10]等方面,,這些研究對羅蘭-C磁天線的接收性能提出了更高的要求,因此需制作靈敏度和信噪比高的磁天線來改善羅蘭-C接收天線的性能,。本文研制了一種順接串聯(lián)的多層線圈的羅蘭-C磁天線,能顯著提高接收靈敏度又能提升其信噪比,,這極大地提高了羅蘭-C磁天線的穩(wěn)定性以及擴大了其應(yīng)用范圍,,具有很重要的實際應(yīng)用價值。
