现代雷达信号处理系统的重要任务之一是抑制地物杂波和消极干扰,提取有用的目标信息。在该系统中,广泛使用了正交通道技术,但在不同的信号处理系统中,正交通道技术起着不同的作用。本文的目的是对雷达信号处理系统中所用的正交通道技术进行总结,并和单通道技术进行比较,使设计人员对正交通道技术有更深入的理解,便于设计时选择最佳方案。
One of the most important tasks of modern radar signal processing system is to suppress clutter and negative interference of ground objects and extract useful target information. In this system, orthogonal channel technology is widely used, but in different signal processing systems, orthogonal channel technology plays a different role. The purpose of this article is to summarize the orthogonal channel techniques used in radar signal processing systems and to compare them with single channel techniques to provide designers with a deeper understanding of orthogonal channel techniques and the ease of selecting the best solution for their design.
