摘要

这封信解决了雷达系统中探测机动目标的挑战,其中距离迁移(RM)和多普勒频率迁移(DFM)显着降低了探测性能。为了克服这些问题,我们提出了一种基于ransac的鲁棒算法,该算法消除了对复杂DFM补偿的需要。该方法首先使用梯形变换(KT)对RM进行校正,然后使用傅里叶变换(FT)进行相干积分。然后采用低阈值恒定虚警率(CFAR)检测器来抑制噪声,同时保留潜在目标点。关键创新点在于利用RANSAC算法对杂乱数据中目标散射点进行鲁棒识别和拟合,有效区分真假报警。仿真结果验证了该方法在具有挑战性的场景下具有良好的鲁棒性和检测能力。

This letter addresses the challenge of detecting manoeuvring targets in radar systems, where range migration (RM) and Doppler frequency migration (DFM) significantly degrade detection performance. To overcome these issues, we propose a robust RANSAC-based algorithm that eliminates the need for complex DFM compensation. The method first corrects RM using keystone transform (KT), followed by Fourier transform (FT) for coherent integration. A low-threshold constant false alarm rate (CFAR) detector is then employed to suppress noise while preserving potential target points. The key innovation lies in using the RANSAC algorithm to robustly identify and fit target scattering points from cluttered data, effectively distinguishing true targets from false alarms. Simulation results validate the method's superior robustness and detection capability in challenging scenarios.
