Abstract

The range-velocity ambiguity caused by the movement of a target has terriole influence on the ranging accuracy of a millimeter wave linear frequency modulated continuous wave short-range radar. A new method was presented to reduce the range-velocity ambiguity and improve the ranging accuracy by estimating parameters of the radar echo signal with fractional Fourier transform and self-correlation .And a new searching algorithm was given to increase computing speed and ranging accura?cy. Compared to Chinese remainder theorem method, the presented method is excellent for its simplici?ty and reducing the computation Durden. The simulation results prove its validity.

Key words
