Analysis of the alarm mechanism for the fan of the SELEX secondary radar receiver unit
In recent years,with the rapid development of the civil aviation industry,secondary radar has been crucial in ensuring the safety of civil aviation flight.The receiver is the core part of the system,with a complex structure and high operating environment requirements.The stability of the entire radar system also depends on a sound alarm mechanism.SELEX_SIR-S secondary radar is taken as an example to introduce the receiver unit fan alarm mechanism and analyze the case of the radar receiver unit fan alarm in detail.Through the introduction of hardware equipment and monitoring signals,the basic function of receiver control and monitoring board and the fan self-test signal detection mechanism of SELEX_SIR-S receiver secondary radar unit are described.
