机载合成孔径雷达实时数字成象处理器的整机控制系统

MASTER CONTROL SYSTEM OF AIRBORNE SAR REAL-TIME DIGITAL IMAGING PROCESSOR

本文对机载合成孔径雷达实时数字成象处理器整机控制系统的系统组成及技术特点进行了研究,扼要阐述了运行在整机控制系统中的实吋操作系统的通讯、任务调度等机制。本文讨论了在实时操作系统中整机控制系统多任务的调度、通讯及多处理器之间的通讯、数据传递等问题,以及实时系统中“人机对话”的问题,并提出了解决问题的方法和系统的控制流程。

The architecture and technical characteristics of the master control system of airborne SAR real-time digital imaging processor (RDIP) are studied. Master Control system (MCS) is designed under the real-time operating system(OS). The real-time (OS) is built around the industry standard real-time executive known as the pSOS + . The pSOS+ supports real-time system by using basic multitask mechanisms, and the real-time OS is designed to perform funtions or tasks in a nonsequential manner. The mechanisms of pSOS+ tasks scheduling, tasks communication and synchronization in the RDIP MCS are discussed. Furthermore the questions about data transporting among tasks and man-machine dialogue also discussed.
