ISAR 데이터로 부터 이동 표적의 탐지 및 표적 신호 성분의 추출
Moving Targets Detection and Signiture Extraction Method from ISAR Data
초록
This paper presents a method not only to detect moving targets from ISAR data corrupted by heavy clutter but to effectively extract the moving targets' signitures that are necessary for acquiring the velocities and images of the targets. In this method, input ISAR data are coherently processed such that echoes due to the moving targets are transformed to be in-phase and then integrated. It is shown that targets' signitures are localized in the transformed two-dimensional domain, leading to dramatic improvement of signal-to-noise (SNR) ration. The extent of the improved signal-to-noise ratio is analyzed and results implemented with simulated ISAR data are presented.
