Title Towed Radar Decoy Recognition and Data Fusion Technology
Abstract
In modern electronic warfare, towed radar active decoy jamming as a new way of interference is an effective method to counter the seeker of pulsed Doppler radar, which has important application value in the field of electronic counter measures, the paper carried out the research and simulation.
In the first chapter, the paper introduces the principle, the type and the development of the towed radar decoy.In the second chapter, the characteristics of target Doppler, the characteristics of the micro - Doppler, the polarization and the statistical features of RCS sequences are discussed in detail.And the Doppler characteristics and micro Doppler features, polarization characteristic,
RCS sequence statistical characteristics, with whose MATLAB simulation, can effectively identify the loading machine and bait,The method of cutting pulse continuation is presented, which can effectively identify the carrier and the bait too.
Paper in the third chapter, in fusion recognition process, primary fusion of the two dimensions of X band vertical polarization and horizontal polarization data can improve the bait recognition rate with the Bayesian data fusion method.Based on the primary fusion, senior integration of features of RCS and Doppler and
the recognition rate of the bait can be reached 100% in a short time.
