摘要
给出了基于Hough变换的信号检测结构,用Weibull分布对加拿大McMaster大学IPIX雷达的某单个距离单元的海杂波幅度数据进行拟合,构造了仿真环境,基于MonteCarlo仿真对基于Hough变换的检测器在非起伏目标和四种Swerling起伏环境下的目标检测性能进行了分析。
The Hough transform based detection architecture is proposed in this paper. Simulation scenario and procedure are designed. Sea clutter data in a single range cell of the IPIX radar is fitted with Weibull distribution. Then, random data obeying Weibull distribution is generated as surrogate of the clutter. The performance of nonfluctuating and four Swerling-fluctuating target detection in surrogate data environment based on Hough transform is analyzed through Monte Carlo simulation runs.
