CFAR Detection of Moving Range-spread Target Based on Waveform Contrast Optimization
摘要
Abstract
In a terahertz high resolution fuze system,relative motions between radar and target can induce high distortions of high-resolution range profiles.These distortions can lead to unacceptable performance deterioration in detection.To solve this problem,an algorithm for detecting moving range-spread targets based on waveform contrast is proposed.The proposed algorithm utilizes the waveform contrast optimization to estimate the relative velocity between radar and target,and then complete the motion compensation and the constant false alarm rate target detection.Therefore,the target detection performance of terahertz fuze can be improved significantly.It is simple and has a good detection effect even for low signal to noise ratio.Simulated experiments are carried out to verify the advantages and effectiveness of the proposed algorithm.关键词
