N2 - Based on the Sino-European cooperation in the Galileo satellite navigation system Search And Rescue(SAR) service, a multi-channel distress beacon signal simulator is presented here. The mathematic model and spectrum analysis of current 406 MHz distress beacons signals is presented which includes Emergency Position Indicating Radio Beacons (EPIRB) for Maritime, Personal Locator Beacons (PLB) for land (road and rail), and Emergency Locator Transmitter (ELT) for aeronautical applications. Based on Software Defined Radio (SDR) and digital IF techniques, the design of a SAR Signal Simulator (SAR-SS) is proposed, which can generate no less than 20 distress signals simultaneously. The Doppler shift and space propagation effect such as ionosphere delay, free space attenuation and etc, are simulated in SAR-SS, which provided a significant test and evaluation capability for SAR/Galileo project. The performance of SAR-SS is more accurate and stabile than the Cospas-Sarsat(C-S) requirement. SAR-SS will be a significant instrument for the Galileo system search and rescue project ground test.
