摘要：a photonics-based radar for high-resolution 3d microwave imaging is proposed and demonstrated, in which high range resolution is achieved by employing a wideband linearly frequency modulated signal, and high cross-range resolution in both azimuth and elevation is realized by rotating the target around two orthogonal axes to compose a 2d inverse synthetic aperture. the proposed radar performs photonics-based in-phase/quadrature up-conversion and de-chirp processing in the transmitter and receiver, respectively, which features a compact structure with low-sampling-rate electronics in the receiver. an experiment is carried out. the established radar works in the $k$ -band, with bandwidth as large as 8 ghz. captured echo signals at different rotation angles of the target are processed to a 3d image, in which the voxel values are scattering intensities at different spatial positions. © 2013 ieee.
