Problems solved by technology

The method is cumbersome, the change of feature points is more complicated, and it is difficult to generate a smooth spatial kill zone by fitting a cluster of vertical kill zones, it takes up a lot of data space, and the real-time performance is weak. It is very inconvenient to form a horizontal kill zone
The traditional analysis method of kill zone requires a large amount of actual data, but in most cases it cannot get enough actual data, especially for some imported or newer models

Abstract

The invention discloses an air defense missile space killing area model construction and shooting data element calculation method based on a small amount of actual data. The method mainly comprises the steps of (1) acquiring air-defense missile data 2) based on the air defense missile data, establishing a space killing area model; and 3) resolving the space killing area model to obtain shooting data.

Description

technical field [0001] The invention relates to the field of application of missile weapon systems, in particular to a method for building a space kill zone model of an air defense missile based on a small amount of actual data and solving the shooting elements. Background technique [0002] The killing zone (killing zone) refers to the space area where the air defense missile weapon system kills the specified air target at a given probability (the space range that kills a typical target with a given probability), and is an important aspect of the air defense missile weapon system. Combat comprehensive performance indicators. The spatial shape of the air defense missile weapon system kill zone is relatively complex, including indicators such as far boundary, near boundary, high boundary, low boundary, maximum route shortcut, maximum route angle, and maximum elevation angle. The general outline of the lethal area is mostly represented by data tables and graphs, most of which...
