Parameter Estimation Accuracy for Radar Targets Closely Spaced in Range

摘要

In this report, we discuss the amplitude, location, and the relative separation estimation accuracy of radar targets closely spaced in range using the Cramer-Rao bound. It is assumed that the phases of successive signals are coherent and therefore contain relative line-of-sight location information. It is shown that this information can substantially reduce the estimation error when compared with the case where the relative signal phase is random. (Author)
