This paper analyzes the factors influencing laser proximity fuze, applies the thought of Fuzzy Comprehensive Evaluation (FCE) and Analytic Hierarchy Process (AHP), builds a simulated environment for testing, sets up a kind of fuzzy comprehensive evaluation model for evaluating the anti-interference ability of laser proximity fuze in a certain interference level.The main results are as follows:1. The effects of target identification and optical detection for anti-interference ability of laser proximity fuze are researched. Several commonly methods of fixing distance and time measuring for laser proximity fuze are analyzed and compared. From the four mechanism of the energy, frequency, spatial and signal processing, the anti-interference technology is studied.2. According to the jamming source in the war field, the jamming mechanisms are analyzed, such as nature factor, laser jamming and passive smoke jamming. Based on research of these factors, the method is established to build a simulated environment for testing.3. By the main parameters of burst distance, detection probability, ranging accuracy, and actuation probability, test techniques and date processing measures are studied, and the performance evaluation methods of a single factor in a certain jamming environment are researched.4. Through learning some evaluate methods for ECM weapon systems, according to the characteristic, we build a method to evaluate the anti-interference ability of laser proximity fuze in a certain interference level by AHP. First, the jamming level of interference environment is defined and evaluated by FCE. Then the factors which decide laser fuze’s performance are evaluated in this environment by AHP and the fuzzy synthetic evaluation model of anti-interference ability is set up. In the end, the example and result shows the validity and feasibility of this method.
