本文以我们提出的移位加权馈相方式为基础,分析了比较简单实用的舍入馈相方式,移位馈相方式,移位加权馈相方式和相位误差均值为零随机馈相方式,找出了一个通用的馈相方程,从而清楚地显现了它们之间的演变关系。还列举了各种馈相方式的指向误差和量化旁(?)的估算公式以及它们的优缺点。由于移位加权馈相方式经过一次布相就可以实现较精确的波束指向,战术的快速搜索雷达应用此法可以提高扫描速度。由于抗干扰的需要,工作频率常常捷变,此馈相方式就显示出其它馈相方式所不具有的优点。因此,对于战术的快速搜索的频率捷变的单脉冲相控阵雷达采用移位加权馈相方式是适宜的。
Based on the proposed shift-weighted feed-forward method, this paper analyzes the simpler and practical method of round feed, shift feed, shift-weighted feed-forward and zero-phase random feed, A common equation of feed-forward is given, clearly showing the evolutionary relationship between them. Also listed a variety of feeding method of pointing error and quantization (?) Estimation formula as well as their advantages and disadvantages. Since the shift-weighted feed-forward method can achieve more accurate beam pointing after a cloth phase, rapid tactical radar search can improve the scanning speed. Due to the need for anti-interference, the operating frequency is often agile, this feed-phase approach shows the advantages of other feed-in methods do not have. Therefore, it is appropriate to adopt a shift-weighted feed-forward method for the frequency-agile single-pulse phased array radar for tactical rapid search.
