Research On Data Field Clustering And Planar Transform Radar Signal Sorting Algorithm

With the advancement of science and technology,there are more and more factors dependent on war.As a "resource" competition between the two sides of the war,there are more "resources" and the possibility of winning.From the beginning of the strength of the forces and the quality of weapons,to the full range of the economy.political.The comprehensive strength of the military is proof of the importance of this "resource".As a limited resource,spectrum is bound to become one of the goals of the two sides.This is electronic warfare.Radar signal sorting plays an extremely important role in electronic warfare,because only the radar pulse signal in the electromagnetic space can be selected to evaluate the threat.Only the decision with sufficient information is the most correct.The battle plans and operational strategies on various battlefields that rely on this threat assessment can be effective.Because radar signal sorting has such an important role,the two sides of the war will naturally study it as much as possible.At the same time of research,in order to prevent their own radar signals from being sorted out,various radar systems are constantly emerging,and radar signals are emerging.The variety is increasing and the forms of change are becoming more complex.In this case,the difficulty of sorting tasks of radar signals is constantly escalating.This paper starts from the rigid demand of radar signal sorting in electronic warfare,and mainly studies the radar signal sorting in complex electromagnetic environment.The main research contents are as follows:Firstly,the current situation of radar signal sorting is analyzed,including the actual electromagnetic environment,various parameters of radar signals and various signal forms extended therefrom,and introduces several classic traditional sorting algorithms,including CDIF and SDIF.And PRI transformation method,etc.Secondly,the traditional clustering algorithm needs to provide parameters artificially.In the clustering process,the concept of the data field is introduced into the cluster because the initial clustering center is easy to cause the local optimal solution and its sensitivity to noise points.,the number of clusters and the cluster center can be automatically confirmed,and the noise point is eliminated by the magnitude of the potential value.The field strength function of the data field is then improved,because the field strength function of the data field describes the way the data object affects other data objects around,and the improved data field improves the stability of the cluster center.Then introduced the principle of plane transformation,studied the sorting effect of plane transform algorithm on various radar pulse signals,combined with the idea of PRI transform to optimize it,reduce the amount of calculation and shorten the running time.Finally,the data field clustering and plane transformation algorithm are used to jointly sort the radar pulses.The simulation results show that the joint sorting algorithm still has good sorting correct results in the presence of pulse loss and interference.
