低截获概率制导雷达设计原理

制导雷达是地对空武器系统的重要组成部分,制导雷达采用低截获概率(LowProbabilityofIntercept,LPI)技术可以提高地对空武器系统的有效性和生存能力。LPI制导雷达实质上是一种从系统上与目标的ESM接收机进行探测灵敏度较量的雷达,因此在系统设计上应着重考虑使其天线主瓣LPI的技术措施。从理论上分析了LPI制导雷达的关键技术和设计方法,并依据典型数据给出了定量的数学模型。

Design Principles for Low Probability of Intercept Guide Radar

Guide radar is an important component of ground to air weapon system.Guide radar using Low Probability of intercept (LPI) technology can enhance the effectiveness and survivorship of ground to air weapon system.Virtually LPI guide radar is a radar which stacks up against with ESM receiver of target in system detection sensitivenes,therefore in the system design it should consider the technology measures emphaticaly to ensure its antenna main lobe LPI capability.This paper analyses the key technology and designed methods of LPI guide radar,and gives quantitative mathematical model based on typical data.
