2、, which fly in the atmosphere (there is no any external thrust). The footprint was calculated and the trajectory was simulated in the first part of paper. The footprint would be determined b

3、y giving different aerodynamic disturbances. The aerial bomb was studied in the second part. Firstly the footprint of certain aerial bomb was fitted by artificial neural network, and a great de

4、al of off- line tests were took to check the accuracy, the larger error was corrected by the 2- D interpolation, this ensures the system to be used in real- time and on- line. Secondly, certai
