脉冲压缩是维持雷达距离分辨率的一种常用方法。 同时增加可以放置在目标上的每脉冲的平均功率。使用全部 这些方法将宽带调制添加到发射的脉冲和滤波器 在接收器中使用与该调制相匹配的调制。有几种这样的 额外的调制,并且每个都有不同的属性,因此模拟这些 在调制器的设计中,方法是必不可少的。在本文中,我们对PULSE进行了概述 给出了压缩技术,这些方法的优缺点是 讨论过。两相编码系统是详细的,因为它们很容易实现 数字硬件。最后描述了我们的仿真硬件和软件工具。 从结果中给出了一些例证。
Pulse compression is a vvidely used method to maintain the range resolution ot radar while increasing the average power per pulse that can be placed on a target. Using all these methods a wideband modulation is added to the transmitted pulse and a filter matched to this modulation is used in the receiver. There are several kinds of these additional modulations, and each has different properties, therefore simulation of these methods is essential during design of modulation. In this article an overview of pulse compression techniques is given, the benefits and disadvantages of these methods are discussed. Biphase coded systems are detailed, because they are easy to implement with digital hardware. At the end, our simulation hardware and software tools are described, giving some illustrations from the results.
