摘要
本文讨论了一种毫米波高分辨率脉冲雷达信号模拟器的设计和实现。用计算机模拟产生毫米波脉冲雷达在各种环境下的视频回波信号,通过高速D/A转换器将模拟结果直接转换成实时雷达视频回波信号。实验结果表明,该模拟器具有真实性好、实时、高分辨率、参数更改方便和可靠性高等特点,可满足毫米波脉冲雷达的测试需要,并可做其它波段的高分辨率脉冲雷达信号处理系统的信号源。
This paper presents the design and realization of a high resolution millimeter wave pulse radar signal simulator. The video returns of millimeter wave pulse radar in all kinds of envi-ronment are produced by computer simulation. The results of simulation are converted directly to real-time video signals by high speed D/A converters. The experimental results show that this simulator has the characteristics of real-time, high resolution, easily changable working parame-ters and high reliability, which satisfies the test requirement for millimeter wave pulse radar and is suited for signal source of signal processing systems of high resolution pulse radars with different wave bands.
