Opto electronic servo control software( OESCS) is an important component of the optoelectronic stabilized platform,engineers pay more and more attention to the debugging problem. This paper starts from the analysis of the characteristics of OESCS,the problems of OESCS'debugging process which is difficult to solve by using traditional method are stated. According to these problems,the specialistic debugging tool for OESCS is designed. The function demand and design essentials are discussed,and the top framework of debugging tool is constructed using the modular programming idea.

Based on analyzing the structure composition of air-to-air missile,referring to the open system architecture for condition-based maintenance( OSA-CBM),the PHM frame model for air-to-air missile is put forward and two case study applying PHM technology on air-to-air missile in service are carried out. By analyzing the factors influencing the performance of missile in store,the parameters needed are determined,requirements on choosing sensor systems according to its cost,shape and transmission mode are given,and condition monitoring system for missile package box is established. Using the parameters adopted in electrical characteristic test and the theory of setting parameter ranges,scoring criteria is set up,and the state indexes of missile is accumulated with weight.

During the laser ranging,the error caused by time-interval measurement error can produce when the pulse width of laser fuze is too wide. So a new range finder method for pulse laser fuze is proposed. The method is first measuring the delay time of transmitted pulse signal and return pulse signal through real-time detecting the center of echo waveform,and then calculating the target range with it. Appling this method a series of range experiments are proceeded,the experimental data are given and the error is analyzed in theory. The results show that the precision of 0. 5 m level is achieved and the ranging precision of the laser fuze is improved,which meets the practical needs.

In order to lower effectively the technical risk of weapon research development,the American Department of Defense( DOD) adopted the notion of Technology Readiness Level( TRL) as well as Technology Readiness Assessment( TRA),and continuously expanded their application field and scope to improve and develop the notion of System Readiness Level( SRL) as well as System Readiness Assessment( SRA). This article introduces the basic concept of TRL and TRA,and then further introduces the basic concept of SRL,SRA and a widely-used assessment method called Matrix-based Model,and applies the assessment method to the airborne guided weapon research development work as a practical instance,presenting an useful reference for TRA of domestic complex integrated systems.
