Abstract:

In order to tolerate radar system errors, the basic topology sequence algorithm rotates topology sequence step by step, which leads to too much calculation burden. A novel singularity value decomposition (SVD) based modified topology sequence matching algorithm is introduced after inferring the approximate linear relation between system errors and topology sequence. Through direct calculation of sequence rotation angle, the modified algorithm not only greatly promotes calculation efficiency, but also avoids the dilemma of selecting angle step size. Through simulation, the SVD algorithm proves reducing calculation time more than 90%. The performance indexes of both correct correlation ratio and false correlation ratio under the same system errors are also promoted greatly.
