This paper deals with the assessment of centralized fusion for two dissimilar sensors for the purpose of tracking road obstacles. The aim of sensor fusion is to produce an improved estimated state of a system from a set of independent data sources. Indeed, for a robust perception of the environment, seen here as obstacles, several sensors should be installed in the equipped vehicle: camera, lidar, radar, etc. In our case, the motivation for this work comes from the need to track road targets with lidar measurements combined with radar ones. Thus, the aim is to combine effectively radar range measurements (i.e. range and range rate) with lidar Cartesian measurements for a "turn" scenario. Centralized fusion, i.e. measurement fusion, for two dissimilar sensors is considered here for assessment which is based on Cramer- Rao Lower Bound (CRLB), the basic tool for investigating estimation performance as it represents a limit of cognizability of the state. In the target tracking area, a recursive formulation of the Posterior Cramer-Rao Lower Bound (PCRLB) is used to analyze performance. Many bound comparisons are made according to the scenarios used and various sensor configurations. Moreover, two algorithms for target motion analysis are developed and compared to the theoretical bounds of performance: the extended Kalman filter and the particle filter.
