Aiming at evaluating radar network detection capabilities, firstly, a multilevel evaluation index system was established by using the fishbone diagram to analyze various complex factors. Secondly, the IAHP-CIM (interval analytic hierarchy process-controlled intervals and memory) model was proposed to evaluate the index system. Specifically, interval analytic hierarchy process was used to solve the problem of quantified fuzzy index, and the interval judgment matrix was obtained; the Shuffled frog leaping algorithm was applied to optimal interval matrix and the certain number matrix with the minimum consistency ration was obtained; the risk probability of indexes were acquired by the controlled intervals and memory model, and synthetically the index system was evaluated. Finally, simulation results demonstrate the feasibility of the proposed evaluation method, and the relatively objectivity of evaluation conclusion are of great significance to optimize arrangement for radar network. 
