In the modern military affairs especially in the complex field the acquirement of real-time battlefield information and intelligence is getting more and more important most of this work is completed by aerial reconnaissance or aerial mapping equipment. Aerial mapping camera with time-sensitive and flexible features is playing an increasingly important role in modern warfare. With the development of technology aerial mapping camera has also gone through several generations gradually from film-based type to transmission type. The theory and composition of domestic and international typical aerial mapping camera is introduced from the development situation and trend in this paper. Finally with the domestic research status the development trend of aerial mapping camera is proposed. 2011 IEEE.

In this paper neural network predictive control method is used to compensate the image forward motion of a certain aerial reconnaissance camera and we have solved several problems that traditional control methods have. Firstly according to the principle of imaging we analyzed the reasons for the existence of image forward motion and established the mathematical model. Secondly we analyzed the theoretically feasibility of the method. At last simulation experiments and test are used to validate the practical feasibility. Through what we have done we conclude that neural network predictive control method can be used to compensate image forward motion for this certain camera and can make a perfect performance. 2011 Springer-Verlag.

The opto-electronic platform is the main equipment for aviation reconnaissance. It is a surveillance system with the function of search recognition orientation and tracking by opto- electronic instruments. It is made up of opto-electronic instruments which are used to get high quality image and stabilization tracking system to control stabilization and gesture of platform for exact tracking. The opto-electronic platform purpose is to achieve high quality image. Besides the impact of optic system the image quality of the system is influenced greatly in the vibration environment. The research worked by Zhao peng which demonstrated the affection caused by angular vibration was worse than which caused by line vibration and what was multiplied direct ratio with plane altitude. So it is necessary to design a new device which could be used widely and has good angular vibration isolation effect. According to the theory of parallelogram the non-angular vibration device had been designed with spatial links and the theory of non-angular vibration was analyzed. The three-dimensional model was set with UG the analysis was done by ADAMS/vibration software. The acceleration and displacement response of the device in each direction was calculated by inspiriting it with sine wave of the acceleration in three directions and the stiffness and damp were studied. All the work prove the design principle of the device is reasonable and the device is adopted to keep the platform motion moving horizontally at the meantime the device is good at isolating vibration in all directions. 2010 SPIE.

A distributed embedded system is designed based on WES(Windows Embedded Studio) which is used to improve the stability and reliability of the aerospace optoelectronic reconnaissance platform and enhance the visualization in the complicated natural environment. This system is combined with the component of distributed data communication the component of CCD image acquisition and transfers all of which are designed on the hardware of PM401 by WES. Then plying the EWF technology integrate the stable and reliable distributed system. At last using NHPP mathematic model analyze the stability and reliability of the system. The results show that the stability and the reliability of this distributed system works well up to 94.61%. 2010 IEEE.
