Abstract This paper introduces a bistatic ISAR imaging technique. In bistatic geometry, the transmitter and receiver are placed in different locations. The monostatic ISAR is inadequate not only for obtaining images on targets approaching along the radar’s line of sight, but also for stealth targets. In this paper, geometry, signal modeling as well as bistatic Doppler for bistatic ISAR are introduced to address these problems. Simulations results show bistatic ISAR images as well as monostatic ISAR images against target’s moving scenarios, and analyze their differences for each scenario.Key words: Bistatic ISAR Image, Bistatic Radar, Bistatic Doppler `%)*abcLd*Le%N=f) /IR /0ghij%kablm, .nopq.r stuL#e^vwueL(Department of Electrical Engineering, Pohang University of Science and Technology) *d*Le%N(Agency for Defense Development)Manuscript received October 7, 2013 ; Revised February 5, 2014 ; Accepted February 10, 2014.
