摘要
本文对数字波束形成技术在雷达系统中的应用进行深入讨论,介绍了数字波束形成的电路设计和波束设计。对于多通道幅相差异的检测和校正,即接收校正和发射校正,给出了详细的工程设计方法和推导公式。试验表明,数字波束形成技术的应用,提高了三坐标雷达的测高精度和系统可靠性。文中的内容在某三坐标雷达产品中已获得成功应用,技术可靠有效。
This paper discusses Digital Beamforming （DBF） in detail for engineering application on radar system, introduces circuit design and beam design of DBF. For test and correction about the amplitude and phase errors among multi-channels, such as receiving correction and transmiting correction, the paper presents a method of engineering design and deduces the formulate. The experimental results also demonstrate application of DBF improved measurement accuracy of height and reliability in 3D radar. The contents applied successfully to the 3D radar product, its technology is reliable and effective.
