Due to the existence of numerous scatters and reflectors, the multipath propagation which leads to false alarms (or ghost images) will be challenging for accurate radar sensing systems in complex environments. In this paper, we use the frequency modulated continuous wave radar to obtain the range-Doppler information of targets. Aiming at the ghost images in low signal to noise ratio (SNR) regimes, we try to extend the existing low-complexity multi-target ghost recognition solution in low SNR regimes. Generally, we try to fuse measurements from different radars and observations, respectively, to improve the target detection quality. Since there exist errors in both range/velocity measurements and radar positions, we adopt a particle based clustering algorithm, to guarantee the robustness of the solution. Simulations and numeric results are provided and analyzed.
