舰载搜索与目标指示雷达系统设计中的一个主要问题是当同时存在地物干扰和人为干扰时要确保系统性能完善而不至于改变系统的工作状态。因此,为了使探测设备能够连续地向武器和指挥控制系统提供数据,要求雷达系统具有自动对抗不同类型的有源干扰和无源干扰的能力,这样战舰就能成功地完成防御或进攻的任务。本文的第一部分介绍了一种采用扫描——扫描频率捷变和相位调制脉冲串技术的雷达系统,该系统是满足上述要求的一种有效手段。
A major problem in the design of radar systems for carrier-based search and target design is to ensure that system performance is improved without changing the working status of the system when there is both terrain interference and man-made interference. Therefore, in order for the detection equipment to continuously provide data to the weapons and command and control systems, the radar system is required to have the ability to automatically counteract different types of active and passive interference so that the warships can successfully accomplish defensive or offensive missions. The first part of this article introduces a radar system using sweep-sweep frequency agility and phase-modulated pulse train technology, which is an effective means of meeting the above requirements.
