The recently developed polyphase-coded FM implementation for physical radar waveforms is generalized to higher-order representations to facilitate greater design freedom (with MATLAB scripts provided in the appendix). Being FM, waveforms realized with these implementations have the benefit of being readily amenable to a high-power radar transmitter while possessing parameterized structures that are advantageous for optimization. Here various attributes of these implementations are examined. Specifically, it is shown that higher-order representations can, in special cases, be made equivalent, and through these relationships appropriate signal structure attributes can be inferred. Higher-order coding guidelines are also derived based on the need to ensure spectral containment. Example waveforms are optimized for each particular implementation to highlight their individual properties, towards the ultimate goal of establishing new ways to realize waveform-diverse emission structures that are physically realizable.

多相编码 FM 雷达波形的高阶实现

最近开发的用于物理雷达波形的多相编码 FM 实现被推广到高阶表示，以促进更大的设计自由（使用附录中提供的 MATLAB 脚本）。作为 FM，通过这些实现实现的波形具有易于适应高功率雷达发射机的优点，同时拥有有利于优化的参数化结构。这里检查了这些实现的各种属性。具体来说，它表明在特殊情况下可以使高阶表示等效，并且通过这些关系可以推断出适当的信号结构属性。高阶编码指南也是基于确保频谱包含的需要而推导出来的。
