A radar signal sorting algorithm based on dynamic grid density clustering
Ju Wang · Modern Electronics Technique · 2013
Aiming at the problems that the fixed grid density clustering algorithm has dependence of the data input and the clustering accuracy is low in radar signal sorting,a radar signal sorting algorithm based on dynamic grid density clustering is proposed. In which the dynamic grid generation technique is used to greatly reduce the number of null grid,the shifting grid technique is employed to eliminate the dependence of data input,and the modified double.density threshold is adopted to im. prove the clustering precision. The algorithm can cluster the data of any size and shape without any parameters input. The experi. ment results show that the algorithm can eliminate noises effectively and cluster the unknown radar signal rapidly and successfully.
