Telescope Array (TA) is a EAS detector which is now building in the western desert in Utah, USA. In order to estimate the performance of TA, a detailed detector simulation is being developed in Java. The number of particles produced during the development of the EAS shower with various inclinations is calculated by COSMOS code. The detection efficiency of each detector is evaluated by using the various calibration data and the results of GEANT4 simulation. And it is taken into account in estimating the signal. The analysis methods of the EAS data are also being developed using TA simulation. This report describes the structure of our simulation code, the analysis methods and the TA performance estimation based on our simulation.
