基于宽窄带微多普勒融合的锥体目标三维重构
A Three-Dimensional Reconstruction Method of Cone Targets Based on Micro-Doppler Fusion of Wideband and Narrowband Netted Radars
摘要
Abstract
Three-dimensional features of targets include delicate structure and micro-motion information.Taking cone-shaped warhead as an object of study,this paper proposes a three-dimensional reconstruction method of cone targets based on the mixed netted radars consisting of both narrowband and wideband ones.Firstly a procession model of cone-shaped target is established,and the micro-Doppler modulation characteristic is analyzed for radar echo in different radar systems.Then the paper,by using the improved algorithm and the least-square theory,extracts and estimates the amplitude and phase information of each scattering center.The gray cognate analysis method is used to correlate those corresponding non-ideal scattering centers.Thirdly,the amplitude and phase information fusion equations in different radar systems are set.Based on the equations,procession parameters and configuration parameters of cone target are calculated to identify the position parameters and realize the three-dimensional reconstruction.The simulation results show that the precision of three-dimensional reconstruction is at about 91% when the signal noise ratio (SNR) is under condition of 5dB.关键词
