聚束合成孔径雷达（SAR）的交叉距离分辨率主要是数据采集角度范围（DeltaPhi）的函数。提高给定DeltaPhi的跨距离分辨率的一种建议方法是使用频变阵列（FDA）技术。目标是利用DeltaPhi的明显增加来提高跨距离分辨率，同时保留更短合成孔径和集成时间的优势。
Cross-range resolution in spotlight synthetic aperture radar (SAR) is primarily a function of the angular extent (DeltaPhi) over which data is collected. One proposed means for improving cross-range resolution for a given DeltaPhi is the use of frequency diverse array (FDA) techniques. The goal is to exploit an apparent increase in DeltaPhi to improve cross-range resolution while retaining benefits of shorter synthetic apertures and integration times.
