**5. Simulation Results**

The effectiveness of the proposed SCM-based JTC method and SMC-JTC-CBMeMBer filter is evaluated by simulations. The observation precisions of range and bearing are σ*<sup>r</sup>* = 1 m and σβ = 0.3◦, respectively. The radar is located at the origin of the coordinates with center frequency *fc* = 35 GHz, bandwidth *B* = 150 MHz, frequency interval Δ*F* = 1 MHz. In this paper, three (*nc* = 3) different ship target classes are considered. The maximum and minimum number of particles used in all the simulations are *L*max = 2000 and *L*min= 300, respectively. The CAD models and the corresponding 3D-SCMs (denoted by a red asterisk "\*") are shown in Figure 2.
