JPDA Joint Probabilistic Data Association for Target Tracking in Clutter Environments with Implementation Considerations
JPDA Probability Data Association and Kalman Filter Implementation for Target Tracking
Implementation of JPDA probability data association and Kalman filtering for two targets moving with constant velocity in the x-y plane. The system adds noise to motion positions, with initial positions at (4000,1200) and (300,1500) and velocities of (200,200) and (400,200) respectively. The sensor measures position states with T=1 sampling interval for 80 points. Detection probability is 1, correct measurement probability within tracking gate is 0.99, and clutter density is uniformly distributed at 2/km² using RAND function for uniform random variables in [0,1]. Tracking gate threshold is set to 9.21.
Data Association as a Core Technology in Multi-Target Tracking
Data association is a critical technology in multi-target tracking. While JPDA is widely recognized as a high-performance algorithm assuming one-to-one measurement-to-target associations, real-world scenarios often involve many-to-many relationships. This paper introduces the Generalized Probability Data Association (GPDA) algorithm to address these complex cases. Theoretically analyzes both algorithms' performance and conducts comparative simulations using Monte Carlo techniques, demonstrating GPDA's superior handling of complex association scenarios.
