Abstract: | In the missile semi-physical simulation system, the anechoic chamber provides a radiofrequency simulation environment, and at the same time it brings an error for the simulation system. This paper proposes a specific error calculation method of the anechoic chamber on the missile simulation system. By modeling the anechoic chamber, it gives a computing method for quiet zone energy, and computes respectively energy for four quadrants of the quiet zone using numerical integration. Then according to the theory for angle estimation characteristic of amplitude comparison mono-pulse radar, this paper computes the angle error of radar on the seeker. Besides, the error is put into the missile simulation system. Simulation result shows that, when adding the anechoic chamber error, the trajectories of the missile and target both shift, decreasing the missile hit accuracy, but the error is still within the error range. |
