摘要
针对日益增强的反恐和安全防护需求,分析了海事卫星信号接收处理的可行性,提出了海事卫星信号接收处理系统的实现方案。该方案在侦测一体化的基础上,通过运用上行信号引导的工作方式,解决了对一定范围内的目标进行抵近接收的问题。与以往的方案相比,所提方案从系统角度研究解决了海事卫星信号接收、解调等关键问题。试验表明,本系统方案能够对实际海事卫星终端的上下行卫星信号进行实时接收处理,具有很好的工程应用价值。
According to the requirement of anti-terrorism and security protection,the feasibility of receiving and processing system for Inmarsat satellite signal is analyzed,and implementation scheme of receiving and processing system of Inmarsat satellite is proposed. Based on reconnaissance and direction-finding integrated technology,this scheme solves the problem of approaching target signal for receiving in a certain range,by applying the operation mode of uplink signal guiding. Comparison with traditional scheme shows the proposed scheme solves the key problem of receiving and demodulation of Inmarsat satellite signal from the system point view. Finally,the tests indicate that uplink and downlink signal of real Inmarsat satellite terminal can be real-time receiving and processing based on proposed scheme,so it has extensive practical value.
