将旁瓣对消器(SLC)应用于旋转天线,要求所用的自适应加权的更新频率,要高到足以避免由于主波束运动而引起的对消性能降低。本文论述采用模——数混合方法的试验性 SLC 的设计和性能。专用数字处理机运用开环算法计算加权,并经乘法数/模转换器将运算结果加到模拟信号通路上去。选用开环算法的目的是避免运用闭环法时所遇到的 SLC 收敛问题。其中一节讲了试验系统的调整技术。本文有试验结果,图示了有效利用 MTI 滤波器来最大限度地减少杂波对样本的影响。用 SLC 可将从23分贝雷达天线旁瓣进入的干扰至少减少12分贝左右。本文还论及了样本量和权更新频率对对消性能的影响。 Applying sidelobe canceller (SLC) to a rotating antenna requires that the adaptively weighted update frequency used be high enough to avoid cancellation performance degradation due to the main beam motion. This article discusses the design and performance of experimental SLCs using the modulo-mixed method. Dedicated digital processor using the open-loop algorithm to calculate the weight, and by multiplication / analog-to-digital converter operation results will be added to the analog signal path. The purpose of choosing an open-loop algorithm is to avoid the SLC convergence problem encountered when applying the closed loop method. One of the sections talks about tuning techniques for test systems. This article has experimental results that illustrate the efficient use of MTI filters to minimize clutter effects on samples. Use SLC to reduce interference from the 23 dB radar antenna sidelobes by at least 12 dB. The paper also discusses the effect of sample size and frequency of right update on cancellation performance.
