Abstract The track of moving target by single photon lidar (SPL) is investigated in marine aerosol environment. The aerosol-induced clutter severely limits the detection performance of SPL. Conventional time-correlated single-photon counting histogram threshold method can only detect static targets. We introduced track algorithm to deal with the discrete scattering point signal of SPL. Furthermore, a two-stage (TS) dynamic model with an adaptive strong Kalman filter was proposed in SPL tracking technique. The proposed method, referred to TS-SKF, has a better performance than the current statistical model with Kalman filter (KF) and the TS model with KF in simulated marine aerosol environment. Finally, a series of field experiments were conducted with a self-established SPL system to track the moving cargo ships over the sea at Qingdao (35.9°N, 120.3°E), China. Both the moving and static targets can be effectively detected with the TS-SKF method. The results show that the proposed real-time processing algorithm can provide a new sight to promote the practical application of SPL.
