Range ambiguity is one of the factors which affect the SAR image quality. Alternately transmitting up and down chirp modulation pulses is one of the methods used to suppress the range ambiguity. However. the defocusing range ambiguous signal can still hold the stronger backscattering intensity than the mainlobe imaging area in some case. https://ashleyshomestores.shop/product-category/4-piece-bedroom-package/
