In this paper, ISAR imaging for a wide frequency range is
explained, by using a proposed method known as Modified Fast Chirp
Fourier Transform (MFCFT). Radar imaging is generally performed in
the L, S and C band frequency, ranging from 1-8 GHz. But, sometimes it
becomes necessary to image a target in wideband frequency i.e., from 1-
40GHz range. Here, in this paper, ISAR imaging is done for wideband (1-
40GHz) frequencies. When imaging is done in this range of frequencies,
the basic methods like RD and RID fails to reproduce images for this wide
range, whereas the proposed method reproduces images with high
