    Abstract :

    In this research a set of microtremor array measuring was performed in site of Shaghayegh Park-Tehran with goal of evaluating the shear wave velocity (Vs) profile for the layers close to the surface. The F-K array processing and SPAC techniques are used and the results are compared with other data particularly a 180 meter depth. The data in different times are compared with the real Vs profile. The results show the SPAC process is more suitable in comparison to the f-k method. SPAC technique shows similar results to the f-k method when few data stations are used for measuring with small dimensions. The dispersion curves obtained through processing each of subarrays were extracted and then compared with the dispersion curve obtained through shear wave velocity profile of Down Hole. At the end our results are compared with previous works and strength points are mentioned. This comparison indicated better efficiency of orthogonal arrays in the mentioned site.The assessment showed better efficiency of orthogonal arrays in the used site.
