Abstract:A method on inhomogeneous sensors coordination direction and cueing is studied for multi-sensor management in C4ISR systems. Firstly, direction and cueing models are derived from azimuth and pitch. Then, direction and cueing areas are discussed based on passive sensor effect range. The direction and cueing errors models are built based on measurement errors and position errors. The direction and cueing probability are computed at last. The simulation results validate the correctness and feasibility of proposed model.
