In order to reduce the burden of pilots and developers and support the plug-and-play of new weapons, a design method of missile-target planning display supporting plug-and-play of weapons is proposed. By constructing the general parameter configuration table of non-guided weapons and guided weapons, and using the script file of configuration parameters for weapon models submitted by manufacturers, the display screen of missile-target planning for attacking targets is automatically generated. The results show that the method only needs to design two kinds of general display pictures of missile-target planning, supports the plug-and-play of new weapons, greatly reduces the burden of pilots and developers, reduces the development cost, shortens the development cycle, and supports the rapid formation of combat effectiveness of weapons.
