摘要

提出了一种在不使用惯性导航系统的情况下，将合成孔径雷达(SAR)脉冲重复频率(PRF)与飞机前进速度实时联系起来的解决方案。利用反射率位移法(RDM)提取飞机前进速度。用于RDM与可变PRF单元耦合的控制系统是一种基于理想开关继电器的非线性自适应控制系统。

Real time motion compensation for synthetic aperture radar

Presented is a real time solution to link the Pulse Repetition Frequency (PRF) of a Synthetic Aperture Radar (SAR) to the aircraft forward velocity without using an Inertial Navigation System (INS). The aircraft forward velocity is extracted using the Reflectivity Displacement Method (RDM). The control system used for coupling the RDM with the variable PRF unit is a non-linearand adaptive one, and based on an ideal on-off relay.
