Research On The Evaluation Of Anti-jamming Capability Of Netted Radar System Based On FAHP

The systematic development of jamming means in modern warfare made thecombat effectiveness of traditional radar greatly reduced, in order to counter enemy’sjamming means more effectively and play its performance better, the developingdirection of radar also aiming at networked and systematic. Making an efficient andreliable evaluation about the netted radar system can make sure all commanders handlethe real-time battlefield status and guide their own network deployment and jammingmethods on enemy’s radar network. Thus, how to effectively evaluate the anti-jammingcapacity of netted radar’s has become an focus in the field of modern radar.This thesis mainly studied the dynamic evaluation index space, evaluation methodand process of the netted radar anti-jamming capacity, mainly contain four parts:1, The network architecture and characteristics of netted radar system are analyzed,the unique advantages of netted radar system when fighting against deception andblanket jamming means are indicated.2, The select rules of evaluate rules about netted radar system are analyzed, thehierarchical anti-jamming capacity evaluation space is established, the redundancy ofindex space is reduced by PCA.3, The anti-jamming capacity of netted radar is evaluated by FAHP based on Fuzzyset and AHP, the judgment matrixes which made by decision maker system are gatheredby group aggregation method, then the preference matrix is sorted by chi-square methodof least squares and the result validated by quadratic programming method.4, The fighting simulation environment of netted radar system and jamming system,then the anti-jamming capacity of netted radar evaluated by weighted approach.The evaluation index space and evaluation method above has been test in asimulation environment built with Matlab, and the effectiveness and ability of theevaluation method is proved by the simulation result.
