An error analysis strategy with random finite set(RFS)is proposed to address the performance evaluation for joint detection and estimation of an extended target with clutters and missed detections. Modeling the state and observations of the extended target as the Bernoulli RFS and Poisson RFS respectively
a mean square error(MSE)bound restricted to maximum a posterior detector and unbiased estimator is derived. Experiments show that the proposed MSE bound can effectively indicate the performance limits of the extended-target joint detection-estimation algorithms and the error is less than 5%.
