Technique of ultra wideband radar target discrimination using natural frequencies

摘要

An aspect independent radar target discrimination method based on the natural frequencies of ultra wideband radar targets is introduced. The sets of points in a multi-dimensional space corresponding to the poles on a complex plane (natural resonances) were offered as signatures of radar targets. This approach allows performing the automated discrimination algorithm of radar targets. The results of experimental research of the signals scattered by scaled aircraft models using the signatures algorithm and cumulant preprocessing are presented.
