Research on the microwave snapshot imaging radar based on antenna array

Based on fast microwave imaging techniques, this paper focus on the research of snapshot imaging radar, which can derive a high resolution image of observed scene, both in spatial domain and time domain. On the basis of imaging geometry and echo model, the paper analyzes the feasibility of microwave snapshot imaging and the restriction between spatial resolution and time resolution firstly. Then, the system constitution and data imaging processing method of snapshot radar are researched. Finally, the feasibility and parameters of snapshot imaging model and system are investigated and verified via a simple pendulum imaging experiment.
