Adaptive ambiguity resolution in automatic-radar design

The paper discusses the problem of ambiguity resolution in the range and velocity dimensions of an adaptive radar. In Part 1, the basic ambiguity problem is introduced, and the principles of ambiguity resolution are developed for the case of a radar which is ambiguous in one dimension only. In Part 2, the simultaneous resolution of ambiguities in range and velocity is considered. Part 3 discusses the impact of the ambiguity resolution requirement on adaptive radar design. The concept of `effective discrimination¿ is introduced, whereby the rate of removal of ambiguity must be moderated if track confusion is to be avoided, and the interdependence of measurements in the two dimensions is clarified.
