数字技术正在渗透于电子设计,特别是雷达领域。本文介绍用数字技术克服模拟技术局限的一些方法,尤其是在波形产生、信号处理及杂波抑制等方面。再以通用计算机是每一部现代雷达的组成部分为例来说明数字技术在雷达中的应用。概括了满足雷达要求的最先进计算机的能力,并预测了未来的潜在功能。 Digital technology is permeating electronic design, especially in the radar arena. This article describes some of the ways to overcome the limitations of analog techniques with digital techniques, especially in terms of waveform generation, signal processing, and clutter suppression. And then the general computer is an integral part of every modern radar to illustrate the digital technology in radar applications. Summarizes the capabilities of state-of-the-art computers that meet radar requirements and predicts future potential.
