| 摘 要： | 针对高分辨率雷达距离扩展目标检测问题，提出了一种基于一维距离像波形的距离扩展目标检测器。分析了目标一维距离像的波形特点，对一维距离像的离散序列进行FFT变换，获得变换后的低频分量平均值与高频分量平均值的比值，以其中最大的比值作为检测统计量并进行有无目标的判决。仿真结果表明，此检测方法的检测性能要优于依赖于散射中心空间分布密度的广义似然比（SSD—GLRT，Spatial Scattering Density—Generalized Likelihood Ratio Test）检测器，并且明显优于基于波形熵的检测器。

| Abstract: | For the range-spread target detection of high resolution radar,a detector based on waveform of one-dimension range profile was proposed.The characteristic of the one-dimension range profile was analyzed,and then FFT(Fast Fourier Transform) was applied to the one-dimension range profile.Moreover,the ratio of average of high-frequency component to average of low-frequency component was obtained,and the maximum of the ratio was used as the detection statistic to judge the existence of the target.The simulation... |
