ISAR turntable experiments using a coherent ultrawideband random noise radar

We have demonstrated that the ultrawideband random noise radar may be used in the ISAR mode. We pursue turntable experiments on various target arrangements containing canonical shapes and structures with emphasis on polarimetry. By using joint time-frequency transforms, we are able to achieve good cross-range resolution. Good slant range resolution is achieved by the ultrawide bandwidth of the transmit signal. Work is also ongoing on combining two orthogonal copolarized images (VV and HH) and a single cross-polarized image (VH or HV) into a RGB color composite image.
