Radar coded aperture imaging for three dimensional target

Two dimensional (2D) radar coded aperture imaging is a cutting-edge imaging technology which can achieve high-resolution, forward-looking and staring imaging. This paper extends the imaging method to three dimensions. Such a three-dimensional (3D) radar imaging technique does not rely on Doppler frequency for resolution and has an extremely short imaging time. 3D radar coded aperture imaging consequently can derive high-quality images for stationary targets. The validity of the proposed imaging technique is confirmed by numerical simulations.
