Microwave Staring Correlated Imaging Method Based on Multi-station Network Radar

摘要

In this paper, we propose a novel Microwave Staring Correlated Imaging (MSCI) method based on multi-station network radar. The proposed method uses multiple radars to transmit random signals synchronously and construct temporal-spatial stochastic radiation fields in the observation area, which have wider observation range and higher imaging resolution compared to single-station radar imaging. This paper deduces and analyzes the MSCI model based on multi-station network radar, which is also suitable for moving targets by utilizing snapshot imaging. Besides, specific time and frequency synchronization method is adopted to improve synchronization precision. Numerical simulation validates the effectiveness of the proposed method and analyzes the effect of time and frequency synchronization's deviation.
