Airborne Phased Array Radar Receiver Real-time Control Technology

This paper explores the application techniques of embedded real-time control in areobone phased array radar receiver.Aiming at the requirement of multifunction and high real-time ability to the areobone phased array radar receiver, a scheme to control the receiver using embedded PC/104 industrial computer and real-time multitask operating system VxWorks is proposed.According to this scheme, applying the computer control technology and on board programming technology, the receiver's controller is designed. Adopting the real-time mutitask design method, the communication task, the hardware control task, time synchronizing task, and error-detecting task are designed to complete the receiver's state control and build-in test in software developing. In this paper, the working priciple, hardware composition and software design of the controller is described in detail.The receiver controller is applied in the aerobone radar which is a part in the key project of national defence. It has been approved that this controller could satisfy the system's requirement, with perfect features in real-time performance, relibity and stability. This will also play an important role on the improvement of the radar receiver and miniaturization of the equipment.
