Dsp Platform-based Modular Radar Signal Sorting Techniques

As one of the important developments of modern radar, radar signal sorting shows great strength in radar signal processing. It has become an important factor of future war in the extreme. Due to the diversiform and complicated radar system, radar signal sorting face much more complex electromagnetic environment. This makes signal sorting software design more complex, and research cycle is shortened. How to design a high quality, efficient, reused system software is the problem every programmer face to.In this paper 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 expression, including:conventional radar signals, the stagger pulse signals, PD signals, jittering pulse signals and frequency agility signals. In addition describes the radar signal processing, including pre-process and the main radar signal processing.Next, we describe how to generate the signals. We focused on the parameters that should consider. Then we studied radar signal PRI sorting algorithms, it include:correlation function algorithm, histogram algorithm (CDIF, SDIF), the PRI transformation algorithm.Choosing the PRI sorting algorithm, we analyse traditional radar signal sorting flow, make three modules:pretreatment, main sorting, and follow disposal. We study the main sorting mainly. And bring up a new algorithm that more suit to real environment. Use reasonable design patterns we realize the radar signal algorithms modularization.In this paper we debate the design of radar signal de-interleaving hardware platform using high performance DSP as kernel. We choose DSP6713 developing system, carry out the key algorithms of radar de-interleaving based on it, and debate optimize question.
