Abstract
Ultra-wideband (UWB) millimeter wave radar has a great advantage for achieving higher spatial resolution and is promising for collision avoidance or target recognition in short range sensing issue. In this paper, we focus on the 140- GHz band radar system, which has a significant advantage for wider frequency range and more compact radar module. For such application, we have originally developed an accurate and high-speed imaging method named as range points migration (RPM), which is based on a 3-D target boundary extraction scheme. This paper introduces the existing RPM radar to achieve fast data acquisition with multiple receivers. To enhance a computational cost and accuracy, we newly introduce the pre- and post-processing algorithms for the original multi-static RPM method, as range points selection and isolated points elimination. Results from numerical simulations assuming 140 GHz radar system, demonstrate that the proposed method accomplishes more efficient 3-D imaging compared with that obtained by the original RPM method.
