With the transition of army operational mission from intra domain to both intra and extra domains, the threats confronted by the army also expand from traditional security to multiple domains such as land, ocean, air, space, network space and electromagnetic spectrum. Under the new mission, the whole domain combat theory of the army is proposed. It emphasizes that the army should be capable of reaching and controlling any region in the space domain; the real time, precision and coordination in the time domain; and highintensity antagonism in the network domain, the electromagnetic domain and even the cognitive domain. The new combat theory requires that the army should focus on strengthening the equipment construction of anti stealth targets, anti ballistic missiles, anti near space vehicles, new concept weapons and information countermeasures, and enhancing the combat capability in the space domain, time domain, network domain, electromagnetic domain and cognitive domain as soon as possible.

The terminal control of an extraatmospheric space vehicle is researched. On the basis of establishing the missiletarget relative motion model, a terminal control law based on the dynamic inverse theory is designed. Through computing the inverse system of the relative motion equation, the adjuster of the line of sight (LOS) angular velocity is designed to make LOS angular velocity approach zero and ensure the encounter precision of space vehicle. Due to adopting the information of target maneuver, the space vehicle can have high precision so as to achieve the high precision strike on the high maneuver target. To cope with the high frequency control problem of orbitcontrol motor, a method of LOS rate doubleenvelope is used to improve the terminal control law based on inverse theory. The simulation results demonstrate the feasibility and validity of guidance methods of space vehicle.

For the problem of wireless communication performance reduction due to sea clutter and severe weather encountered in real time images transfer used for battlefield environment monitoring, SPIHT image Compression Algorithm based on wavelets is presented in this paper for the application in airdefense weapon system, using simulation to verify the effectiveness of this algorithm. Compression code stream from infrared seeker images can be generated by image compression for transfer substitution to improve image transfer rate. Simulation result shows that lossless compression ratio is 3 and loss compression ratio could be 32 for 256×256 8 bits gray level infrared image without visual effect reduction. The research achievement can provide theoretical basis for airdefense infrared seeker image compression transfer implementation.
