基于稀疏Radon变换的窄带雷达信号单目标检测方法

本文提出了应用于窄带雷达信号的单目标检测方法：基于稀疏 Radon 变换的方法， 该方法适用于低信噪比的情况，需将目标能量校正到一个距离单元后对方位向调频率进行搜索。 在原有雷达单目标的检测方法基础上，适当地进行相位补偿，并使得目标回波相干化，最终提出了两种应用于窄带雷达单目标的检测方法，利用了稀疏 Radon 变换，验证了目标检测方法的有效性，并在此基础上，实现了对目标的运动参数的准确估计。

Single Target Detection Method Based on Sparse Radon Transform of Narrow-Band Radar Signal

This paper proposes a single target detection method applied to narrow-band radar signals: a method based on sparse Radon transform. This method is suitable for low signal-to-noise ratio conditions. The target energy needs to be corrected to a range unit and then the direction modulation frequency is adjusted. On the basis of the original radar single target detection method, proper phase compensation is carried out and the target echo is made coherent. Finally, two detection methods applied to narrowband radar single target are proposed. The sparse Radon transform is used to verify the target detection. The method is effective, and on this basis, the accurate estimation of the target''s motion parameters is achieved.
