To realize the in-situ detection of the aircraft radio altimeter in out-field,the in-situ detector for the altimeter was developed by taking the industrial personal computer(IPC)PC104 and embedded processor STM32 as the system core,in which the design thoughts of the functional block diagram and each module,software functional partitioning and architecture are provided. The detector can implement the altimeter signal isolation and the voltage conversion,generate the altitude simulation signal and analog signal of the indicator,and provide the check signal of the altimeter to indicate the normal signal and alarm trip signal,and to measure the linear and nonlinear altitude voltage. The design has realized the simple and friendly human-com-puter interaction,and has been used and verified in the aviation test.
