Generate Random 3D Target Trajectories

In target tracking algorithm research, generating realistic 3D target trajectories is essential for testing and validating tracking algorithm performance. A flexible trajectory generation tool can simulate targets with different motion characteristics, such as UAVs or aircraft movements in three-dimensional space.

This MATLAB package allows users to customize altitude range, velocity range, and acceleration range parameters to generate diverse 3D motion trajectories. By setting these parameters, users can create motion models in simulation environments that meet practical scenario requirements. For example, UAVs may cruise at low altitudes with slow speeds or perform high-speed maneuvers at high altitudes.

The trajectory generation logic is based on random motion models that ensure smooth variations within specified ranges. The program can adjust motion constraints as needed, such as limiting acceleration to prevent unrealistic sharp turns or sudden stops. Implementation typically involves coordinate system transformations and kinematic equations to maintain trajectory continuity. The generated trajectories can be used to test the robustness of Kalman filters, particle filters, and other tracking algorithms, particularly their performance under complex motion conditions.

For researchers, this tool provides a rapid method for building test datasets, eliminating the tedious process of manual trajectory design, thereby allowing greater focus on tracking algorithm optimization and analysis. The code structure typically includes configuration files for parameter settings, main generation functions with randomization algorithms, and visualization modules for trajectory plotting and analysis.
