“…This is not as critical for frequency modulated continuous wave (FMCW) radar architectures where the system is continuously transmitting and receiving. However, the use of FMCW radar architectures for SAR imaging have their own complications such as intrapulse range migration [18].…”

“…Uncorrected deviations from the assumed trajectory exceeding 0.1 λ introduce significant phase errors and deteriorate the quality of SAR images [2]. In some authors' opinion the fully focused SAR imaging requires the positioning accuracy better than 0.25 λ [3]. The carrier frequency of the radar sensor used in our experiments is equal to 2.91 GHz, therefore λ = 0.1034 m. The above mentioned requirement poses a great challenge for the navigation system.…”
