Cooperative Detection Analysis Based on Cramer-Rao Low Bound

In this paper, a cooperative interception problem is considered. Cooperative detection analysis for multiple flight vehicles is essential to the cooperative guidance and the relative configuration between the flight vehicles has an influence on the measurment. Therefore, the cooperative detection performance based on the Cramer-Rao low bound is analyzed. First, the dynamic model and the cooperative detection model are established. Then the Cramer-Rao low bound is formulated and the detection performance based on the CRLB of the relative distance between the flight vehicles and the target is analyzed. Then, three cases of simulation is conducted to analyze the detection further more. Finally, the optimal relative configuration of the vehicles is acquired.
