| Popis: | In the high-frequency PD radar engineering applications, it is easy to produce the distance ambiguity problem. The most commonly used solutions of the fuzzy algorithms are Chinese remainder theorem, one-dimensional set of algorithms and more than poor look-up table method. This paper presents a new algorithm of range ambiguity resolution, first of all estimate a set of fuzzy distance number of wavelengths through the lattice theory, and then implement the estimation of the true distance in the framework of maximum likelihood estimation. Finally, the simulation experiments show that, the solution of fuzzy algorithm under the assurance to solve the ambiguity of the accuracy of the premise, compared to in the Chinese remainder theorem, one-dimensional set algorithm, residual look-up table method has a faster processing speed. |
