Simulation Model for Detection Probability of Ground Air Defense Early-warning Radar

With full consideration of the problems of testing the detection effectiveness of ground air defense early-warning radar by experiments, this paper sets up a more complete simulation model for the probability of radar detection by combining the analytic computation of target discovering probability with the simulation of radar functions. This model includes the modules of estimation of visibility range, solution of SNR, calculation of jamming power and etc., as well as some simulation links. And this model can be based on the typical aircraft targets＇ track cenarios to simulate and compute the single radar and/or radar network＇s integrated detection probability of targets＇ all track points, thus providing the technical support for simulation test of the detection effectiveness of ground air defense early-warning radar equipment and the study of operational use. Finally, it is effectively proved that this proposed model is of availability by performing the simulation experiments on multi- levels and granularity.
