Abstract：As an important weapon specialized for attacking objects on the ground (or sea) the airborne air-to-surface missile plays a unique role in modern combat. Improving the precision of weapon system is essential to strengthen the combat ability of air-to-surface missile. In a word, the study of precision analysis has outstanding significance. Firstly, the paper introduces the basic index system of precision analysis, analyzes errors influencing the weapon system of missile and discusses fall point precision and statistical rule of fall point distribution. Based on the fundamental theories, the train of thoughts to analyze precision of air-to-surface missile is formed. The precision is discussed in two aspects: fire control system and guidance system and fall point precision is used as evaluation index. Secondly, we setup the whole system model and precision analysis model of air-to-ground television remote control missile based on analyzing properties of errors. The established mathematical models are simulated by using the Monte Carlo method. Finally, the simulation has been conducted and the result analysis show the validity of precision analysis.
