引言自从最初使用雷达以来,雷达操作手均以平面位置显示器(PPI)和 A 型显示器上的视频输出来检测和跟踪目标。操作手虽能非常精确地完成这些任务,但这时他们非常紧张,并且很快会感到疲劳。为了改变这种情况,在许多雷达中都添加了自动检测与跟踪(ADT)系统。毫无疑问,由于增加了数字处理的速度和降低了硬件的成本和尺寸,因而除最简单的雷达外,自动检测与跟踪系统几乎与其他一切雷达都有关。本文的目的是评述自动检测和跟踪的技术发展状况。本文将讨论提供目标放大用的各类 INTRODUCTION Since the inception of radar, radar operators have used PPIs and video outputs on Type A monitors to detect and track targets. Operators can do these tasks with great accuracy, but they are very tense and quickly tired. In order to change this situation, automatic detection and tracking (ADT) systems have been added to many radars. Undoubtedly, with the addition of the simplest radar, the automatic detection and tracking system is almost as relevant to every other radar as it increases the speed of digital processing and reduces the cost and size of the hardware. The purpose of this article is to comment on the state of the art in automatic detection and tracking. This article will discuss the various aspects of providing a target zoom
