Abstract

This paper presents a prototype of high resolution millimeter-wave ISAR, which is composed of both commercial-off-the-shelf and low-cost designed-specific components. The radar transmits a CWLFM signal in a frequency range from 95.4 to 104.4 GHz, inside a window of atmospheric attenuation. The paper covers both the description of the system components and the assessment of its performance through turntable-imaging experiments. The image formation processor implements the well-known polar formatting algorithm.
