| 摘 要： | 宽带雷达目标回波表现为多散射点子回波的合成,各子回波幅度、频率、相位具有一定的随机性,造成一个重复周期内各子回波信号能量难以有效积累,严重影响宽带雷达目标检测性能.针对此问题,提出利用RELAX算法实现宽带雷达目标多散射点子回波精确分离,对各子回波幅度相加实现多散射点回波能量相参积累,提高输出信噪比,从而增强宽带雷达的目标检测性能.仿真及实测数据处理结果表明所提出的方法应用于宽带雷达重复周期内多散射点回波能量相参积累是有效的. |

| Abstract: | The echo of a target,stimulated by wideband waveform,is the combination of signals of multiple scattering centers.The randomness of the amplitude,frequency and phase in each signal is the main factor to affect the in-pulse efficient coherent integration,and causes disadvantages to wideband radar target detection.To solve this problem,the RELAX algorithm is used to decompose the echo signal of each scattering center,then the amplitude in each signal is accumulated together to increase SNR,so the target detection performance of wideband radars is developed.The validity of the method is verified by computer simulations and real data processing results. |
| Keywords: | wideband radar RELAX algorithm coherent integration target detection |
