The invention discloses a method for quantitatively evaluating the guiding capability of a radar station, and belongs to the cross field of early warning detection and military operation. Based on the guiding operation flow of the radar station, according to the queue theory, the radar station is regarded as a random service system. The guiding capability of the radar station is quantitatively analyzed and evaluated by constructing an air-strike weapon model, an own force model, a dynamic guiding model and the like, in combination with a computer simulation technology, adopting an event drive simulation method and through Monte Carlo test, so that the problem that quantitative evaluation lacks in the dynamic guiding process of the radar station is solved, and the method is beneficial to specifically strengthening and perfecting the construction of the radar station, optimizing and guiding resource configuration and promoting the air defense combat capability.
