Based on the analysis of effectiveness, the paper establishes mathematics model of assaulting area, as well as kill probability launching area and effectiveness launching area of some type air-to-air near-range missile.

The computation model of the single-shot kill probability of antiaircraft missile under the electronic jamming condition is built.

Aircraft single threat hit vulnerability is usually expressed as the kill probability or vulnerable area.

In the survivability/vulnerability assessment for aircraft,the kill probability and vulnerable area of aircraft at certain threat hits always require to be provided.

Results of simulation indicate the gain which can improve missile kill probability in the direction fuze-warhead system.

Aimed at shooting characteristic of high power laser air defense weapon,the killing probability is discussed by probability theory.

The killing probability of fragmentation warhead of missile to air target and its influence factors were analyzed.

Based on the killing characteristic of anti-air missile,a model is established to evaluating an anti-air missile s killing probability by analyzing the effective fragments generated after the warhead explosion,the velocity of the fragments,and the covering area of these fragments.

The engineering calculation method for the lethal probability of the blast-fragmentation warhead exploding in the air was introduced.

A certain warhead with prefabricated fragments was calculated,the density and lethal probability of the fragments field were described and the variety curve of the lethal areas with exploding height in different falling angles was obtained.

The kill probability for single missile is the key index for evaluating the combat effectiveness of weapon systems with long-range air-to-air missiles.
