    气象传真接收机是船舶在航行中获取水文气象资料的主要手段。现在气象传真接收机大多采用模拟电路实现,导致接收机数字化程度不高,不便于气象信息的有效利用。本文针对现在气象传真接收机问题,在基带信号处理算法基础上,结合了气象传真信号自身的特征,提出了FM的解调方案以及对应算法,并对解调算法在MATLAB平台上做仿真和验证,最后验证了算法的科学性和可行性。 The weather facsimile receiver is the main means by which the ship obtains hydrometeorological data during navigation. Now most of the weather fax receivers using analog circuits to achieve, resulting in the digitization of the receiver is not high, not easy to use the effective use of weather information. In this paper, based on the problem of meteorological facsimile receiver, based on the characteristics of meteorological facsimile signal itself, the demodulation scheme and corresponding algorithm of FM are put forward, and the demodulation algorithm is simulated and verified on MATLAB platform , And finally verify the scientific and feasibility of the algorithm.
