An Improved Step-Transform Algorithm for High Squint SAR Processing

  • An improved step-transform algrithm is proposed for high squint mode synthetic aperture radar(SAR). It uses different chirp rates to deramp the signal in different subapertures to alleviate the varying of chirp rate with the azimuth time, and to accurately select data from the coarse-resolution FFT output by approximate interpolation in frequency-domain and to remove the tight constrains for the parameter in time-varying step-transform. The performance of the algorithm is efficient in high squint mode.
