Abstract: A radar system uses a rotating antenna array having rows that display dispersive properties while feeding multiple radiating elements. In some embodiments, the radiating elements are dual polarized. In at least one embodiment, beam spoiling may be used to generate an unfocused transmit beam that covers an entire elevation range of interest. Digital beam forming may be used during a receive mode to achieve a stack of narrow-width receive beams in elevation. Frequency scanning may also be used to achieve stacked beams in azimuth.

Abstract: Methods and apparatus for a phase array radar system having a fragmented array. In one embodiment, subarrays forming a generally rectangular shape are disposed on the surface of a truncated cone or a dome so that gaps are formed between adjacent segments of subarrays or between every adjacent subarrays.

Abstract translation: 雷达系统使用旋转天线阵列，其具有在馈送多个辐射元件的同时显示色散特性的行。 在一些实施例中，辐射元件是双极化的。 在至少一个实施例中，波束破坏可用于产生覆盖感兴趣的整个高度范围的未聚焦的发射波束。 可以在接收模式期间使用数字波束形成，以实现在高度上的窄宽度接收波束的堆叠。 也可以使用频率扫描来实现方位角的堆叠梁。
