Research And Implementation On Coherent Integration Of Passive Radar Based On Multicore DSP

With the development of modern war, electronic counterm easure technologyconstantly updates and progresses.In the face of the threat of electronic interference andanti-radiation missiles,the survival environment of traditional active radar is gettingincreasingly serious.Different from active radar,passive radar does not radiateelectromagnetic waves,but make use of non-cooperation radiation source to detect and tracktargets,which has incomparable advantages in aspects of concealmentand anti-stealthcompared with active radar.Furthermore,passive radar has already become a new researchfocus for many countries in the radar field.In recent years,Chinese digital televisionterrestrial broadcasting (DTTB) has been developing rapidly,the signals it transmits offeringa new ideal radiation source for passive radar.This paper mainly researches and thecoherent Integration of Passive Radar Based on Multicore DSP,base on the supports of theNational Natural Science Foundation of China,and finally put forward a completeapplication scheme implemented on the existed hardware platform.The research results of this paper have a high practice value,The main contents aresummarized as follows:Introduces the background and significance of this project,shows an overview of thecoherent Integrational gorithms.Discusses the basic theory of the array antenna, analyzesthe features of ULA.Proposed a method to improve coherent Integration performance basedon digital beam forming.Analysis the method to achieve moving target detection of passive radar based onZoomFFT and Doppler spectrum analysis, simulation,and compares.Work out theconclusion that the Doppler spectrum analysis method improves the computationalefficiency of coherent integration of passive radarIntroduces the features and development process of multi-core DSP TMS320C6678,illustrates the use of each module.Achieve the Doppler Spectrum algorithms,make full useof the computing ability of c6678.
