现代雷达信号处理的数字脉冲压缩方法

脉冲压缩技术是雷达信号处理的关键技术之一。文中主要从信号形式、优势和不足、应用场合等方面介绍线性调频、巴克码、多相码、非线性调频等几类常用脉冲压缩信号，提出在时域和频域实现数字脉冲压缩的统一数学模型，推荐了相应的工程实现方法。根据具体雷达的目的和不同类脉压信号的特性，设计最佳脉冲压缩滤波器是提高雷达脉冲压缩性能的关键。

Methods of Digital Pulse Compression in Modern Radar Signal Processing

Pulse compression technology is an important technology of radar signal processing. This paper introduces some pulse compression signals about their signal styles, advantages and defects, applicability, etc. These pulse compression signals are liner frequency modulated signal, Barker code, polyphase code and nonlinear frequency modulated signal. The paper provides a uniform mathematic model to implement digital pulse compression in time-domain and frequency-domain. It recommends corresponding implement methods of digital pulse compression. To design the best pulse compression filter according to special radar purpose and different pulse compression signals is the key to improve the ability of radar pulse compression.
