Abstract:

To ensure the stable operation of the airspace stabilization loop and the locked airspace of  the airborne radar antenna do not change with changes of aircraft air attitude,a ground test system is designed to detect loop‘s steady operation state.Basic requirements are  based the airspace stable circuit function and performance testing,test system hardware and software implementations are provided.Computer control and automated testing techniques are used.It is possible to test automated and precisely locate the fault.The application shows that the test system with advanced technology,simple operation,easy maintenance,stable operation,made  a significant military and economic benefits.

Key words: the airspace stabilization loop, coordinate transformation, test system
