Abstract

The mission in missile systems can be conducted with multiple phases according to the characteristics of the systems and the targets. The safeguarded multi-phase mission includes a safeguarded phase before launch for considering the safety of operators in unexpected squib activation. However, the safeguard function should be disabled after launch to complete the mission. Therefore, the squib system needs to be selectively activated according to the phases. This paper presents a selective squib activation and check circuit design for safeguarded multi-phase missions in missile systems. The presented circuit design was implemented with various electronic components including a field-programmable gate array(FPGA). Its functions and performance were validated by both many ground tests and several flight tests.
