Abstract: This paper endeavors to give some basic concepts of fuze S & A environment recognition on the basis of which the performance of the traditional S & A systems is analyzed- It puts forward the information theory aspects concerning S & A environment recognition，and classifies the S & A environment recognition into environment detection and pattern re?cognition. Based on a brief description of the information theory aspects concerning S & A environment recognition， the information value of environment con?dition is defined. Taking into account the relationships between the infor-mation source? the method of recognition，and objectives of the environment recognition device, a theoretical model is developed and formulae for quan?titative evaluation of the information values are deduced. The paper sets up a criterion of evaluation for environment detection and analyzes the conceptual basis of design in traditional S & A. A general description is given on pattern recognition and three basic principles are formulated.
