Research on Forward-Looking Imaging Technology Based on Maneuvering Motion

Radar forward-looking imaging has important application value in target attack and terrain detection. However, traditional synthetic aperture radar (SAR) cannot perform high-resolution imaging of the area directly in front of the flight trajectory, due to the limitation of mechanism. This paper proposes a new airborne forward-looking imaging scheme based on maneuvering motion. The scheme firstly starts from the movement trajectory of the platform, gives the spatial geometric relationship of the forward -looking imaging, and establishes the echo signal model, further analyzes the azimuth resolution characteristics of the signal. On this basis, combined with the phase characteristics of the echo signal, a forward-looking imaging algorithm suitable for this scheme is derived. Finally, through simulation experiments, the target imaging results are analyzed to verify the effectiveness of the algorithm.
