摘要
有源相控阵雷达中的电源管理模块在工作过程中易受到干扰,导致程序跑飞,传统的抗干扰措施能使软件复位到初始状态。为了保证雷达工作不间断,提高单片机系统的可靠性,设计了软件系统的崩溃-恢复机制。当系统受到干扰复位后,根据备份信息,自动恢复到系统崩溃之前的工作状态。并通过试验验证了该方案的可行性。
Under bad industrial condition,the power management module of AESA radar may loss control because of interfere.The traditional anti-interference measures only can make software reset and back to the initial condition.This paper designs a breakdown-resume mechanism to improve the reliability of MCU and guarantee the working of radar uninterrupted.When the system crashed,this mechanism can make the system return to the state before the crash automatically according to the backup information.Then verify the feasibility of this mechanism through a test.
