摘要
提出了一种通用雷达信号模拟器的实现方法。该方法采用通用计算机产生雷达回波数据,利用打印机接口实现PC机向外设传送数据,采用D/A变换器产生模拟视频回波信号;它具有极大的灵活性和通用性,只要改变计算机的软件,就可以实现不同体制雷达回波的模拟,解决了硬件设计和软件算法中的关键技术问题。
The paper provides a method by which general-purpose radar signal simulator can be realized. The method uses general-purpose computer to generate radar echo data,printer interface to transmit data from PC to peripheral equipment, and D/A converter to form simulated video echo signal. The method is of significant flexibility and commonality. So long as the computer software is changed, simulation of different radar system echoes can be implemented. The key technical problem in hardware design and software algorithm is therefore solved.
