In this paper, ISAR imaging for a wide repeat range is figured out, by using a proposed methodology known as Modified Fast Chirp Fourier Transform (MFCFT). Radar imaging is generally acted in the L, S and C band repeat, going from 1-8 GHz. However, a portion of the time it becomes essential to picture an objective in wideband repeat i.e., from 1-40GHz region. https://www.theijire.com/archives/paper-details?paperid=10&papertitle=execution-of-wideband-radar-to-isar-imaging-using-enhanced-fast-chirp-fourier-transform
