A target velocity measurement method in submillimeter step frequency radar

A target velocity measurement method based on positive and negative step frequency waveforms is presented in this article. Using the characteristic of positive and negative step frequency waveforms, three signal process methods are introduced. With these methods we can get different velocity resolution and unambiguous velocity range. Combining these methods we can get the precise target velocity without ambiguity. A signal process flow and Matlab simulation are given in the end.
