In order to evaluate the effectiveness of the troop reconnaissance equipment scientifically, reasonably and intuitively, an evaluation method of the effectiveness of the troop reconnaissance equipment based on the improved radar chart method is proposed. First of all, according to the characteristics of the troop reconnaissance equipment in active service and the effectiveness of the equipment in use, an evaluation index system of the effectiveness of the reconnaissance equipment is established, and based on the linear scale transformation method, the effectiveness index of the above reconnaissance equipment is normalized. Secondly, the index scale method is utilized for determining the weight of effectiveness evaluation index of reconnaissance equipment, solving the problem of inaccurate weight calculation of other weight scale method. Then, , the improved radar chart method is utilized for solving the problem that the evaluation result is not unique because of the inconsistent evaluation index sequence. . Finally, an example is given to verify the correctness and rationality of the proposed model.
