Abstract
A broad review of publications relevant to nonlinear radar is conducted. The principle-of-operation of nonlinear radar is summarized and applications for this technology are listed. Targets addressed by this type of radar follow a power-series model, and from this model a nonlinear radar range equation is derived. An extensive survey of publicly-available literature, including specifications for systems already tested, guides the design of harmonic radar for finding electronics. The authors have combined a stepped-frequency architecture with harmonic radar to create a system which is capable of imaging and tracking nonlinear targets with very high clutter rejection.
