摘要

提出了一种用于聚焦近场谐波雷达的双频恒波束宽反射天线。该技术通过指定LPDA顶点角，将反射器离焦效应与对数周期偶极子天线馈源的频率相关相位中心位移相匹配。通过仿真和实测验证了该技术的有效性。

A constant beamwidth reflector antenna for a harmonic radar operating in the near-field

A dual-frequency constant beamwidth reflector antenna for use with a harmonic radar in the focused near-field is proposed. The technique matches reflector defocusing effects to the frequency dependent phase center displacement of a log-period dipole antenna feed by specifying the LPDA apex angle. The technique was verified by simulations and measurements.
