摘要
低截获概率雷达是雷达电子对抗技术的一种。随着电子对抗技术的发展，
提高雷达的生存性就显得越发重要。从雷达的研制设计阶段就引入低截获概率
的观念，在不影响战技指标的前提下利用相关技术，降低雷达的被截获概率是
电子对抗技术发展方向之一。本论文根据电子对抗技术的发展，引入低截获概
率雷达的概念，并从截获因子的数学模型中分析影响截获因子α的主要因素，
提出脉冲压缩技术是提高机载雷达低截获概率特性的主要方法之一。最后，就
脉冲多普勒（PD）雷达实现数字脉压技术进行仿真，并对其可行性进行了分析。
Low桺robability梠f桰ntercept(LPI) radar technology is one of the
radar electronic counter countermeasure technologies With the
development of electronic countermeasure technologies, it is getting more
and more important to enhance the survival of radar0 Introduction of the
LPI concept at the design stage of radar and lowering the probability of
intercept using related LPI techniques without effecting radar s
performance is one of the technology development direction of electronic
counter countermeasure,, In this paper, LPI radar concept was introduced
based on the development of electronic counter countermeasure
technologies0 Major factors that affect the intercept factor a were got
from the mathematics model of intercept factor0 Based on this analysis
it is recognized that pulse compression technique is the major method for
enhancing the LPI performance of airborne radar0 An airborne Pulse Doppler
radar using digital pulse compression technique was simulated and the
feasibility of its implement is analysed0
