摘要
随着电子战技术的发展,舰载雷达接收环境的日益恶化,现代雷达接收机向着大动态范围方向发展。分析了舰载雷达接收机由于干扰引起的过载,介绍了灵敏度时间控制、瞬时自动增益控制、对数放大器及限幅放大器四种舰载雷达接收机抗过载的方法。
The environment of shipborne radar receiver is getting worse and worse along with the development of electronic warfare technology. The modern radar receiver develops towards the direction of large dynamic range. This paper analyses the over-load of shipborne radar receiver due to jamming, introduces four anti-over-load methods of shipborne radar receiver, namely sensitivity time controt（STC） method,instantaneous automatic gain control（IAGC） method,logarithmic amplifier method and limiting amplifier method.
