Intensive Signal Under The Conditions Of Radar Signal Sorting

As one of the important developments of modern radar, radar signal sorting shows great strength in radar signal processing. It will be an extremely important factor of future war and is focused at home and abroad, also has a wide range of civil and military values.This paper studies in radar signal sorting technology. The background and the importance of the research have been mentioned first, together with the research situation at home and abroad. Then we introduce the theory of radar signal processing and some radar PRI expression, including: conventional radar signals, the stagger pulse signals, jittering pulse signals and frequency agility signals. The flow of radar signal processing has been listed, including the preconditioning process and the process.Next, we describe how to generate the signals. Especially we focused on the parameters, including the time, the angles, the frequency, the amplitude and the density. Then show the details of how to generate the signal pulse, the interference pulse, the combination and the pulse description word (PDW).Whereafter, PRI sorting algorithms and the comprehensive analysis are adopted and compared. PRI sorting algorithm include: correlation function algorithm, histogram algorithm (CDIF, SDIF), the PRI transformation algorithm, the radar plane transformation algorithm, and the comprehensive analysis. The last item contains the pulse extraction and the separation method of the stagger signals.Based on the multi-parameter K-MEANS clustering algorithm and dynamic association algorithm, we introduce a new algorithm. Then list the principles, the steps, the results of the simulation. From some simulation, we can get a good result.
