This work aims to address vulnerabilities in radar tracking systems caused by adversarial electronic countermeasures.
Developed a coherent DRFM architecture for active jamming using non-linear phase perturbation.
Performed simulations to evaluate tracking performance under adversarial conditions.
Implemented ECCM strategies using KL divergence auditing to stabilize tracking.
Demonstrated severe tracking collapse with range oscillations exceeding 10 meters under adversarial conditions.
Achieved stabilization of terminal tracking range errors down to 0.2 meters using information-gated ECCM.
