A microwave lens that is based on the principles of holography is described. It consists of a zone plate, and it has been shown theoretically and experimentally that it has the limit of resolution, which is predicted by the aperture and the wavelength used.

An imaging microwave radiometer†
International Journal of Remote Sensing, 1983Abstract The phase A study of an imaging microwave radiometer (IMR) has been completed, for ESA, by a team of contractors led by BAe. The instrument design which was established during this study is described in this paper. The IMR would be able to measure the intensity of radiation in the microwave band at a number of specific frequencies.

Radar breast imaging (RBI) involves the illumination of the breast with a microwave pulse. If a tumour is present, backscattered radar signals are generated due to the dielectric contrast between normal and tumour tissue at microwave frequencies. These backscattered signals are processed by an RBI beamformer to identify the presence and location of any

Multidimensional microwave imaging
Microwave and Optical Technology Letters, 1995AbstractThe high computational load associated with multidimensional high‐resolution algorithms is overcome by using only 1D LP techniques. The 3D backscattered field is approximated by three 1D AR models that are solved in succession for the down‐range, horizontal cross‐range, and vertical cross‐range positions of the scattering centers of a target.
