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.
