一种小型自动化检测与录取设备的设计
摘要
雷达录取设备主要用来完成来自雷达信号处理机的信号的相关检测和录取、输出一次视频、对信号处理机工作方式的控制、产生模拟目标等功能。雷达目标识别技术是通过数据采集与预处理、特征提取、匹配分类等信号与信息处理手段,处理从雷达背景噪声中的提取的目标回波信号,从而实现自动判别未知目标的类别与属性目标识别技术的关键是如何从雷达检测录取单元中获得实时准确的目标数据,检测与录取分系统作为目标识别系统前端,是整个识别系统重要组成部分之一,其工作的好坏,将直接影响目标识别雷达在军事上的运用。
当前,雷达正朝着规范格化、标准化的方向发展,自动录取设备也面临着越来越高的要求。现在自动录取设备不但要具有强大的处理能力,还要有灵活的对外接口、多样化的处理手段。同时,为配合整个终端的变化,自动录取设备需要有较小的体积,高可靠性及低廉的成本。为满足上述要求,本文阐述了一种采用以ADI公司生产的ADSP21060芯片与大规模EPLD器件为核心的设计思路,实现在一套硬件平台上不同的检测方法。
The radar extractor is used for the signal detection and extraction in radar processor, which can send out the primary video frequency and control the working modes of radar processor, meanwhile come into being analog target signal. The technology of target recognition is used to automatically identify the category and attribute of an unknown target, which based on the echo signal from the background clutter which will be processed by some signal processing methods including data acquisition and pre-processing, feature extraction and matched sorting. The key technology of target recognition is how to obtain the real-time and exact target data from the radar extractor. As the former unit in the system of target recognition, the signal detection and extraction is one of important subsystem, which success or not will influence the military application of target recognition radar.
In the current, with the developing radar standardization, the requirement for radar automatic extractor is becoming more and more strict, besides with the feature of powerful processing capability, flexible interface function and operating diversification, the extractor should also be small-sized, high-reliability and low-cost facing to the different requirements and market competition. In order to satisfy the above features, the design of a small-sized and automatic signal detection and extraction equipment which can realize the different methods signal detection and extraction by using the ADSP21060 chip made by ADI Lt. Co and large-scale EPLD apparatus in one suit of hardware platform is presented in this paper.
