摘要
多通道间幅相不一致会影响三维成像雷达的成像质量。针对步进频率体制三维成像雷达,分析了系统窄带部分通道间幅相不一致对目标三维(距离、方位角、俯仰角)成像的影响,并提出了一种基于中频注入补偿信号的补偿方法。
The quality of imaging can be affected by amplitude phase inconsistency between channels of multichannel three dimensional imaging radar.In view of MMW step frequency HRRM three dimensional imaging radar,the effects on range profile and angle testing due to the channel inconsistency on the part of narrow band are analyzed respectively.A compensation method based on the signal inject is developed.
