Aircraft altitude estimation method based on multi-beam pitching sum and difference channels for SAR

Aircraft altitude estimation method based on multi-beam pitching sum and difference channels for SAR

Synthetic aperture radar (SAR) can provide high-resolution two-dimensional radar images of the target area. The error of the altitude between aircraft and the target area causes geometrical distortion of the SAR ground image, which is unfavourable for scene matching and target recognition. Existing...
