High-frequency vibration error of a moving radar platform easily introduces a non-negligible phase of periodic modulation in radar echoes and greatly degrades terahertz synthetic aperture radar (THz-SAR) image quality. For solving the problem of THz-SAR image-quality degradation. the paper proposes a multi-component high-frequency vibration error estimation and compensation approach b... https://www.thecookiecountesses.shop/product-category/pens-and-markers/
