Abstract: Aiming at the naval point air raid scale forecast problem, the composition of the air attack system is analysed firstly. And calculation models of dispatch intensity, demand and air raid formation scale are established for the number estimation of air raider. Then a configuration region model of long-range support jammer is established, in which the dispatch number is estimated by judging whether the corresponding disposition areas could be intersected for di erent target radars. Also, one estimation model for escortsupport jamming plane with mixed formation is established. And then, a cruise missile estimation model related with the air raid effect is established. Calculation examples show that models in this paper can be support for the air attack scale forecast of naval point.
