| 摘 要： | 幅相失真及通道间幅相不一致会影响多通道三维成像雷达的成像质量。针对毫米波频率步进体制的HRRM三维成像雷达,将不一致性分为高频宽带不一致和中频窄带不一致两大部分,分析了高频部分频率特性失真和通道间不一致性对目标三维(距离、方位角、俯仰角)像的影响,并对高领部分的频率特性按成像的要求提出了设计指标。

| Abstract: | The imagining quality will be affected by amplitude phase distortion and interchannel amplitude phase inconsistency. Based on the MMW stepped frequency HRRM 3D imaging radar, this paper introduces two kinds of inconsistency, i.e. broadband inconsistency and narrowband inconsistency, and analyzes the effect of the frequency characteristic distortion and interchannel inconsistency on ranging and angle measurement. Moreover, the paper puts forward the design indexes of the high frequency subsystem. |
