This paper focuses on the operational configuration calculating of passive smoke jamming equipment for fixed positions,and the improving of the operational decision-making capability of the commander and the applicational efficiency of the equipment.First,an analysis is made to the principle of passive smoke jamming calculation.Second,the procedure and steps for calculating the positions and quantity of the jamming equipment are expounded in detail.At last,the practicability of the calculation method is verified by an example analysis.It is proved that this method has certain theoretical and practical value for operational planning.
