Featured Projects

Python · PyTorch · PINN Jul 2025 – Present

EW-Resilient Multi-Sensor Threat Tracking & Trajectory Prediction

Real-time kinematic state estimation and continuous-time trajectory prediction under active electronic countermeasures (radar noise jamming, RGPO, and packet drops).

▹ Asynchronous multi-rate sensor fusion (Radar 10Hz, EO/IR 30Hz, ESM 5Hz) via continuous Time2Vec and cross-attention reliability gating.
▹ Continuous-time PINN decoder with exact C¹ boundary pinning (p(0)=p₀, ṗ(0)=v₀) and autograd structural load factor limits (|Nz| ≤ 9.0G).
▹ Multi-target correlation (2–8 aircraft), GNN/JPDA association, and inter-track collision avoidance validated via OSPA/GOSPA.
▹ Profiled for 100 Hz tactical mission loops on embedded NVIDIA Jetson Orin (1.08 ms forward latency via TensorRT FP16).
